mtd: rawnand: Add destructive operation

Browse source

Erase and program operations need the write protect (wp) pin to be
de-asserted to take effect. Add the concept of destructive
operation and pass the information to exec_op() so controllers know
when they should de-assert this pin without having to decode
the command opcode.
