mtd: OneNAND: multiblock erase support
Add support for multiblock erase command. OneNANDs (excluding Flex-OneNAND)
are capable of simultaneous erase of up to 64 eraseblocks which is much faster.
This changes the erase requests for regions covering multiple eraseblocks
to be performed using multiblock erase.
