752fe75910 mimxrt/machine_spi: Improve handling of busy SPI peripheral.
This commit changes the method of waiting for SPI being not busy.  Instead
of the FIFO size, the TransferBusyFlag is probed.

Also, raise an error if the transfer failed.

b70b8ce3e4 mimxrt/machine_rtc: Start RTC at boot and set datetime if not set.
Changes in this commit:
- Start the RTC Timer at system boot.  Otherwise time.time() will advance
  only if an RTC() object was created.
- Set the time to a more recent date than Jan 1, 1970, if not set.  That is
  2013/10/14, 19:53:11, MicroPython's first commit.
- Compensate an underflow in in timeutils_seconds_since_2000(), called by
  time.time(), if the time is set to a pre-2000 date.

1f6cb8f047 mixmrt/machine_i2s: Add I2S protocol support.
This commit adds support for machine.I2S on the mimxrt port.  The I2S API
is consistent with the existing stm32, esp32, and rp2 implementations.

I2S features:
- controller transmit and controller receive
- 16-bit and 32-bit sample sizes
- mono and stereo formats
- sampling frequencies from 8kHz to 48kHz
- 3 modes of operation:
  - blocking
  - non-blocking with callback
  - uasyncio
- configurable internal buffer
- optional MCK

Tested with the following development boards:
- MIMXRT1010_EVK, MIMXRT1015_EVK, MIMXRT1020_EVK, MIMXRT1050_EVK
- Teensy 4.0, Teensy 4.1
- Olimex RT1010
- Seeed ARCH MIX

Tested with the following I2S hardware peripherals:
- UDA1334
- GY-SPH0645LM4H
- WM8960 codec on board the MIMXRT boards and separate breakout board
- INMP441
- PCM5102
- SGTL5000 on the Teensy audio shield

e0b97013d0 mimxrt/hal/pwm_backport: Make PWM symmetric, and round division calcs.
Ensure the symmetry of PWM: the duty rate of X and Q channels was not 50%,
when it should have been.  That is evident at high frequencies, like 15Mhz
or 37.5 MHz.  At low frequencies the deviation mattered less.  The A/B
channels were fine.

Also round up or down non-integer division factors. Before, always the
floor value was used.

b0d460cd7d mimxrt/eth: Fix an Ethernet transmit error.
Sometimes frames could not be sent immediately because the controller was
still busy with previous frames.  Then, an error was returned to lwip.
This fix adds a limited number of retries for this busy state, waiting
100µs before the next attempt.  Typically the transmit succeeds now at the
second attempt.

Second change: Reset the controller for a clean state after soft reset.

1dc366f901 mimxrt: Replace Pin-config constants by a function call.
The Pin config setting by IOMUXC_SetPinConfig() is supplied by a
bit pattern. That pattern is specific for a MCU family. In preparation
for supporting the MIMXRT117x family, the constant bit pattern is
replaced by a function call, such that the bit pattern is created
at a single place. The code for this functions was taken from
machine_pin.c.

1892d03740 mimxrt,stm32: Enable MICROPY_PY_USSL_FINALISER.
This is needed because these ports allocate mbedtls data on the MicroPython
heap, and SSL socket objects must be fully cleaned up when they are garbage
collected, to free this memory allocated by mbedtls.  As part of this,
gc_sweep_all() will now ensure that the MP_STATE_PORT(mbedtls_memory)
linked-list is fully deallocated on soft reset.

c5dbbf71c0 mimxrt: Use -Og instead of -O0 for DEBUG builds.
Thanks for the hint, Damien. The DEBUG build got very large recently.
The major difference is, that inline function are now inlined and
not included as a function. That's good and maybe bad. The good thing is,
that the code speed si now close to the final code. It could be worse
in single step debugging. I'll see.

Setting this option caused a new warning and a formatting error
to pop up at different places. Fixed as well.

1e9eaa7af5 mimxrt: Add a driver for the DP83848 PHY device.
Just another choice for the PHY interface.

Added: Keyword option phy_clock=LAN.IN or LAN.OUT

interface. The RMII clock is not enabled if it

LAN.IN  The clock is provided by the PHY board.
LAN.OUT The clock is provided by the MCU board.

The default is LAN.OUT or the value set in mpconfigboard.h, which
is currently set to IN only for the SEEED ARCH MIX board. Usage etc:

lan = LAN(phy_type=LAN.PHY_DP83848, phy_clock=LAN.IN)

81f706aee4 mimxrt: Support PWM using the FLEXPWM and QTMR modules.
Frequency range 15Hz/18Hz to > 1 MHz, with decreasing resolution of the
duty cycle.  The basic API is supported as documentated, except that
keyword parameters are accepted for both the instatiaton and the
PWM.init() call.

Extensions: support PWM for channel pairs.  Channel pairs are declared by
supplying 2-element tuples for the pins.  The two channels of a pair must
be the A/B channel of a FLEXPWM module.  These form than a complementary
pair.

Additional supported keyword arguments:

- center=value Defines the center position of a pulse within the pulse
  cycle.  The align keyword is actually shortcut for center.

- sync=True|False: If set to True, the channels will be synchronized to a
  submodule 0 channel, which has already to be enabled.

- align=PWM.MIDDLE | PMW.BEGIN | PWM.END. It defines, whether synchronized
  channels are Center-Aligned or Edge-aligned.  The channels must be either
  complementary a channel pair or a group of synchronized channels.  It may
  as well be applied to a single channel, but withiout any benefit.

- invert= 0..3. Controls ouput inversion of the pins.  Bit 0 controls the
  first pin, bit 1 the second.

- deadtime=time_ns time of complementary channels for delaying the rising
  slope.

- xor=0|1|2 xor causes the output of channel A and B to be xored.  If
  applied to a X channel, it shows the value oif A ^ B.  If applied to an A
  or B channel, both channel show the xored signal for xor=1.  For xor=2,
  the xored signal is split between channels A and B.  See also the
  Reference Manual, chapter about double pulses.  The behavior of xor=2 can
  also be achieved using the center method for locating a pulse within a
  clock period.

The output is enabled for board pins only.

CPU pins may still be used for FLEXPWM, e.g. as sync source, but the signal
will not be routed to the output.  That applies only to FLEXPWM pins.  The
use of QTMR pins which are not board pins will be rejected.

As part of this commit, the _WFE() statement is removed from
ticks_delay_us64() to prevent PWM glitching during calls to sleep().
