NOTE: I don't know the appropriate VID/PID -- It's currently using the 1060_evk settings and not the teensy settings. Not sure which to use

Description of Change

This commit adds support for the Teensy 4.0 and 4.1 boards.

It modifies the ports/mimxrt10xx/tusb_config.h and boards.c so that either USB port 0 or usb port 1 can be used. This is useful for any IMXRT1062 based board. Though less useful for the teensy 4.0 because it doens't have that port pinned out.

I believe I addressed all the issues with 9db2504e0443c3b80858c4e6203ef4e05cc2f2de. I ran and verified that things still work on teensy 4.1 and 4.0, and that the PIDs are correct, and that the boot disks show up with the new names.
