Jim Mussared f46782dde9 mimxrt: Add new, minimal port to NXP i.MX RT series CPUs.
This is an extremely minimal port to the NXP i.MX RT, in the style of the
SAMD port  It's largely based on the TinyUSB mimxrt implementation, using
the NXP SDK.  It currently supports the Teensy 4.0 board with a REPL over
the USB-VCP interface.

This commit also adds the NXP SDK submodule (also from TinyUSB) to
lib/nxp_driver.

Note: if you already have the tinyusb submodule initialized recursively you
will need to run the following as the tinyusb sub-submodules have been
rearranged (upstream):

    git submodule deinit lib/tinyusb
    rm -rf .git/modules/lib/tinyusb
    git submodule update --init lib/tinyusb
