5e990cc27f mimxrt: Add support for MIMXRT1176 MCUs, and MIMXRT1170_EVK board.
The RT1176 has two cores, but the actual firmware supports only the CM7.
There are currently no good plans on how to use the CM4.

The actual MIMXRT1170_EVK board is on par with the existing MIMXRT boards,
with the following extensions:
- Use 64 MB RAM for the heap.
- Support both LAN interfaces as LAN(0) and LAN(1), with LAN(1)
  being the 1GB interface.

The dual LAN port interface can eventually be adapted as well for the
RT1062 MCU.

This work was done in collaboration with @alphaFred.

94beeabd2e py/obj: Convert make_new into a mp_obj_type_t slot.
Instead of being an explicit field, it's now a slot like all the other
methods.

This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

6da41b5900 py/obj: Merge getiter and iternext mp_obj_type_t slots.
The goal here is to remove a slot (making way to turn make_new into a slot)
as well as reduce code size by the ~40 references to mp_identity_getiter
and mp_stream_unbuffered_iter.

This introduces two new type flags:
- MP_TYPE_FLAG_ITER_IS_ITERNEXT: This means that the "iter" slot in the
  type is "iternext", and should use the identity getiter.
- MP_TYPE_FLAG_ITER_IS_CUSTOM: This means that the "iter" slot is a pointer
  to a mp_getiter_iternext_custom_t instance, which then defines both
  getiter and iternext.

And a third flag that is the OR of both, MP_TYPE_FLAG_ITER_IS_STREAM: This
means that the type should use the identity getiter, and
mp_stream_unbuffered_iter as iternext.

Finally, MP_TYPE_FLAG_ITER_IS_GETITER is defined as a no-op flag to give
the default case where "iter" is "getiter".

a316a8fdb3 mimxrt: Use MP_REGISTER_ROOT_POINTER().
This uses MP_REGISTER_ROOT_POINTER() to register all port-specific root
pointers in the mimxrt port.

a0432ed9cb mimxrt: Update port to work with new nxp_driver v2.10.
The nxp_driver v2.10 allows for/requires some changes to the code:

- Remove some part of pwm_backlog.*, which is provided by the lib now.
- Change eth.c: the newer versions have additional parameters of the
  library versions.
- Change sdcard.c: use TransferBlocking instead of TransferNonblocking.
- Add some support for the MIMXRT1176 device.
- Set the clocks for UART, I2C, Timer.
- Integrate the I2S module and fix a rebase error.
- Use blocking transfer only for SPI.  It's faster and interferes less with
  other modules.
- Use the clock_config.c files of library v2.8.5.  The mimxrt files keeps
  the clock_config.c files from Verson 2.8.5.  With clock_config.c from
  v2.10, the boards do not work.  Refactoring of the clock set-up is on the
  to-do list.
- Enable expiry timers for UART, I2C and SPI, avoiding a stall in library
  code.
- The clock_config.* files are moved from the board-specific directories to
  the boards directory and given a MCU related name.

0e7bfc88c6 all: Use mp_obj_malloc everywhere it's applicable.
This replaces occurences of

    foo_t *foo = m_new_obj(foo_t);
    foo->base.type = &foo_type;

with

    foo_t *foo = mp_obj_malloc(foo_t, &foo_type);

Excludes any places where base is a sub-field or when new0/memset is used.

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
