Subject: AVR32 MTD: Unlock flash if necessary
From: Haavard Skinnemoen <hskinnemoen@xxxxxxxxx>
If a cfi_cmdset_0002 fixup installs an unlock() operation, use it to unlock
the whole flash after the erase regions have been set up.
I wanted to do this in the fixup itself, but it wouldn't work because the
erase regions hadn't been initialized, and mtd->size was zero.
