colibri_t20: fix/hack sd boot environment
We wrongly set an obsolete define so the U-Boot environment ended up at
the wrong location on the SD card.
Add a hack introducing a short delays before doing MMC_CMD_SET_BLOCKLEN
as otherwise all 4GB Kingston or SanDisk cards I have failed.
While at it fix the USB port naming in the device tree comments to
adhere to the standard Colibri convention.
