e33db80a59 samd/clock_config: Extend the SAMD51 us-counter to 60 bit.
This removes the difference in the time.ticks_us() range between SAMD21 and
SAMD51.

The function mp_hal_ticks_us_64() is added and used for:
- SAMD51's mp_hal_ticks_us and mp_hal_delay_us().
  For SAMD21, keep the previous methods, which are faster.
- mp_hal_ticks_ms() and mp_hal_tick_ms_64(), which saves some bytes
  and removes a potential race condition every 50 days.

Also set the us-counter for SAMD51 to 16 MHz for a faster reading of the
microsecond value.

Note: With SAMD51, mp_hal_ticks_us_64() has a 60 bit range only, which is
still a long time (~36000 years).

fc9d66fac6 samd/machine_rtc: Add the machine.RTC class.
Methods implemented are:
- rtc.init(date)
- rtc.datetime([new_date])
- rtc.calibration(value)

The presence of this class can be controlled by MICROPY_PY_MACHINE_RTC.  If
the RTC module is used, the time module uses the RTC as well.

For boards without a 32kHz crystal, using RTC makes no sense, since it will
then use the ULP32K oscillator, which is not precise at all.  Therefore, it
will by default only be enabled for boards using a crystal, but can be
enabled in the respective mpconfigboard.h.

2251cb774b samd/machine_uart: Implement uart.txdone() and uart.flush().
Using the stream method for uart.flush().

uart.txdone() returns True, if the uart not busy, False otherwise.

uart.flush() waits until all bytes have been transmitted or a timeout
triggers.  The timeout is determined by the buffer size and the baud rate.

Also fix two inconsistencies when not using txbuf:
- Report in ioctl as being writeable if there is room in the tx buffer,
  only if it is configured.
- Print the txbuf size if configured.

f0399d35e4 samd/modmachine: Get the bootloader magic address from the lib.
Instead of being hard-coded, and then it works for all MCUs.

That fits except for a Sparkfun SAMD51 Thing Plus (known) bug, which uses
192k - 4 as magic address.  Therefore, that address is set as well to avoid
a problem when this bug is fixed by Sparkfun.

03075a6839 samd/modmachine: Implement machine.lightsleep().
Which just sets the CPU clock to 200kHz and switches the peripheral clock
off.  There are two modes:

    machine.lightsleep(duration_ms)

and

    machine.lightsleep()

In any mode any configured pin.irq() event will terminate the sleep.

Current consumption in lightsleep for some boards:
- 1.5 - 2.5 mA when supplied trough an active USB
  (Seeed XIAO w/o power LED, Adafruit ItsyBitsy)
- 0.8 - 2 mA when supplied through Gnd/+5V (Vusb)
  (Seeed XIAO w/o power LED, Adafruit ItsyBitsy)
- < 1 mA for SAMD51 when supplied trough a battery connector
  (Sparkfun Thing SAMD51 plus)

Related change: move the calls to SysTick_Config() into set_cpu_freq().  It
is required after each CPU freq change to have ticks_ms run at the proper
rate.

1c32cec7f1 samd/clock_config: Support changing machine.freq() for SAMD21.
The range is 1MHz - 48 MHz.  Note that below 8 MHz there is no USB support.
The frequency will be set to an integer fraction of 48 MHz.  And after
changing the frequency, the peripherals like PWM, UART, I2C, SPI have to be
reconfigured.

Current consumption e.g. of the Seeed Xiao board at 1 MHz is about 1.5 mA,
mostly caused by the on-board LED (green LED with 1k resistor at 3.3V).

edc3f3d0d3 samd/clock_config: Extend the range of machine.freq().
The value given for machine.freq(f) is extend to the range of 1_000_000 to
200_000_000.  Frequencies below 48 MHz will be forced to an integer
fraction of 48 MHz.  At frequencies below 8 MHz USB is switched off.  The
power consumption e.g. of ADAFRUIT_ITSYBITSY_M4_EXPRESS drops to about
1.5 mA at 1 MHz.

Since the peripheral frequency is dropped as well, timing e.g. of PWM,
UART, I2C and SPI is affected and frequency/baud rate has to set again
after a frequency change below 48 MHz.

1ba0e8ff96 py/persistentcode: Only emit sub-version if generated code has native.
In order for v1.19.1 to load a .mpy, the formerly-feature-flags which are
now used for the sub-version must be zero.

The sub-version is only used to indicate a native version change, so it
should be zero when emitting bytecode-only .mpy files.

8874a09119 extmod/mbedtls: Enable elliptic curve DH and DSA cryptography.
This is necessary to access sites that only support these protocols.

The rp2 port already has ECDH enabled, so this just adds ECDSA there.  The
other ports now gain both ECDH and ECDSA.  The code size increase is:

- rp2 (PICO_W): +2916 bytes flash, +24 bytes BSS
- stm32 (PYBD_SF6): +20480 bytes flash, +32 bytes data, +48 bytes BSS
- mimxrt (TEENSY41): +20708 bytes flash, +32 bytes data, +48 bytes BSS
- unix (standard x86-64): +39344 executable, +1744 bytes data, +96 BSS

This is obviously a large increase in code size.  But there doesn't seem to
be any other option because without elliptic curve cryptography devices are
partially cut off from the internet.  For use cases that require small
firmware size, they'll need to build custom firmware with a custom mbedtls
config.

d6d8722558 extmod: Make extmod.mk self-contained.
This makes it so that all a port needs to do is set the relevant variables
and "include extmod.mk" and doesn't need to worry about adding anything to
OBJ, CFLAGS, SRC_QSTR, etc.

Make all extmod variables (src, flags, etc) private to extmod.mk.

Also move common/shared, extmod-related fragments (e.g. wiznet, cyw43,
bluetooth) into extmod.mk.

Now that SRC_MOD, CFLAGS_MOD, CXXFLAGS_MOD are unused by both extmod.mk
(and user-C-modules in a previous commit), remove all uses of them from
port makefiles.
