robert-hh 98c5703027 mimxrt/machine_i2c: Add hardware-based machine.I2C to machine module. 
It uses non-blocking transfer of data.  Advantage over SoftI2C:
- Higher data rate up to ~3 MHZ.
- Full protocol support.

Port of MicroPython to NXP iMX RT 10xx

Currently supports Teensy 4.0 and the i.MX RT1010 EVK board.

Features:

  • REPL over USB VCP
  • machine.Pin

Known issues:

  • pyboard.py doesn't work with files larger than 64 bytes
  • machine.Pin class currently does not support GPIOMUX option of i.MX RT101x variants

TODO:

  • Enable TCM
  • Peripherals (LED, Timers, etc)
