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.
