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

4ce1adab31 mimxrt/boards: Remove conditional assignment of flash type/size.
Removes conditional assignment because respective variables should only be
set in board makefile fragments.  Hence no conditional assignment needed.

bec0524dbf mimxrt/Makefile: Rework board flash type handling.
Reworks handling and configuration of different board flash types in the
Makefile, linker scripts and board makefile fragments.

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.

c7accf7666 mimxrt/boards/OLIMEX_RT1010: Document the initial deploy procedure.
The procedure given here will work whether or not the DevKit motherboard is
used and is equipped with the support MCU.  It is laborious but works.

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

da9c3607a5 mimxrt: Add support for the Olimex RT1010 board.
The board.json file is intentionally excluded, until the board will be
sold. But including it into the mimxrt series make it easier to keep
the build up-to-date.
