Subject: [PATCH v4 06/15] mtd: nand: kill the MTD_NAND_IDS Kconfig option

MTD_NAND_IDS is selected by MTD_NAND, which makes it useless. Remove the
Kconfig option and link nand_ids.o into the nand.o object file.
Doing that also prevents adding an extra nand_ids.ko module when MTD_NAND
is activated as a module.
