mtd: nand: Move Toshiba specific init/detection logic in nand_toshiba.c
Move Toshiba specific initialization and detection logic into nand_toshiba.c. This is part of the "separate vendor specific code from core" cleanup process. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Richard Weinberger <richard@nod.at>
