robert-hh 99221cd118 mimxrt: Fix cycle counter for time.ticks_cpu() and machine.bitstream(). 
Prior to this commit mp_hal_ticks_cpu() was not started properly.  It only
started when the code was executed with a debugger attached, except for the
Teensy (i.MXRT1062) boards.  As an additional fix, the CYYCNT timer is now
started at boot time.

Also rename mp_hal_ticks_cpu_init() to mp_hal_ticks_cpu_enable().

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)
