util/chromeos/crosfirmware: ensure $BOARD is lowercase

If $BOARD is not all lowercase, then certain subfunctions of the
script will fail due to case-sensitive comparisons therein. To avoid
this, since all matched strings are fully lowercase, set $BOARD
to lowercase.

TEST: './crosfirmware.sh {akemi/Akemi/AKEMI}' all succeed.
