Damien George 7408ca1d78 mimxrt: Improve ticks and sleep functions using GPT. 
SysTick cannot wake the CPU from WFI/WFE so a hardware timer is needed to
keep track of ticks/delay (similar to the nrf port).

Fixes issue #7234.

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

Known issues:

  • pyboard.py doesn't work with files larger than 64 bytes

TODO:

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