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.

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.

Note: A working port for the MIMXRT1176 exists already.

7e62c9707a mimxrt/sdram: Add SDRAM support.
Adds support for SDRAM via `SEMC` peripheral. SDRAM support can be
enabled in the mpconfigboard.mk file by setting `MICROPY_HW_SDRAM_AVAIL`
to `1` and poviding the size of the RAM via `MICROPY_HW_FLASH_SIZE`.

When SDRAM support is enabled the whole SDRAM is currently used used
for MicroPython heap.

87f97e490c mimxrt/sdcard: Implement SDCard driver.
- Configures `PLL2->PFD0` with **198MHz** as base clock of
	`USDHCx` peripheral.
- Adds guards for SDCard related files via `MICROPY_PY_MACHINE_SDCARD`
- Adds creation of pin defines for SDCard to make-pins.py
- Adds new configuration option for SDCard peripheral pinout
        to mpconfigport.h
- Adds interrupt handling support instead of polling
- Adds support for `ADMA2` powered data transfer
- Configures SDCard to run in HS (high-speed mode) with **50MHz** only!

SDCard support is optional and requires `USDHC` peripheral.
Thus this driver is not available on `MIMXRT1010_EVK`.
SDCard support is enabled by setting `MICROPY_PY_MACHINE_SDCARD = 1`
in mpconfigboard.mk.

b8c65b174f mimxrt/machine_adc: Add the ADC class to the machine module.
This adds the machine.ADC class with the read_u16() method.  make-pins.py
and supporting files are updated to generate ADC information.

ff5d39529c mimxrt: Implement machine.Pin class.
- modified pin type from pin_obj_t to machine_pin_obj_t
- created machine_pin.c
- implemented basic version of make-pins.py to genertate pins.c/.h files
  automatically; the only alternate function currently supported is GPIO
- added af.csv files for all supported MCUs
- replaced pins.c/pins.h files with pin.csv for all boards
- implemented on/off/high/low/value/init methods
- Implemented IN/OUT/OPEN_DRAIN modes
- modified LDFLAGS for DEBUG build to get usefull .elf file for debugging

02cc4462b7 mimxrt: Add initial impl of machine.LED class, and basic pin support.
This commit implements an LED class with rudimentary parts of a pin C API
to support it.  The LED class does not yet support setting an intensity.

This LED class is put in the machine module for the time being, until a
better place is found.

One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.
