This commit adds the necessary configuration and hooks to get the CYW43
driver working with the mimxrt port.

Add portable pin config macros to mphalport.h. And add a function to
configure pins with more pin options such as alt function, pull, speed,
drive, interrupt mode, etc.
Note: this new `machine_pin_config()` function can replace
`machine_pin_set_mode()`, but the latter is left as-is to avoid breaking
anything.

When called without a handler, the IRQ data was not cleared. That caused a
crash at the second soft reset in a row.

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.
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.

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.
- 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
