mtd: nand: Remove support for block locking/unlocking
Commit 7d70f334ad2b ("mtd: nand: add lock/unlock routines") introduced support for the Micron LOCK/UNLOCK commands but no one ever used the nand_lock/unlock() functions. Remove support for these vendor-specific operations from the core. If one ever wants to add them back they should be put in nand_micron.c and mtd->_lock/_unlock should be directly assigned from there instead of exporting the functions.
