linux_mtd: Support for NO_ERASE type devices

Some mtd devices have the MTD_NO_ERASE flag set. This means
these devices don't require an erase to write and might not have
implemented an erase function. We should be conservative and skip
erasing altogether, falling back to performing writes over the whole
flash.

BUG=b:35104688
TESTED=Zaius flash is now written correctly for the 0xff regions.
