tc2: add blank.img

blank.img is placed where the UEFI config is stored.

When the user first flashes their board with the firmware, blank.img
(which is all zeros) will be written to the NOR flash, effectively
erasing the UEFI config.

Then, when UEFI starts, it will spot that the config is blank and create
a default set.

Subsequent reboots will not re-write blank.img, so the config will
persist.

Users can also erase the UEFI config manually by updating the timestamp
of blank.img and rebooting the board.
