Some raw NAND function names conflict with names defined in nand.h.
Prefix all those functions with nandc (for nand chip) instead of nand so
we can include nand.h from rawnand.h

BBT support is currently tightly tied to raw NAND, though this is the kind
of code we could share across all NAND based devices, no matter what
physical interface is to communicate with the NAND chip.
Make BBT code interface agnostic by replacing all occurrence of
struct nand_chip by struct nand_device, and move functions that are
specific to raw NANDs to drivers/mtd/nand/rawnand/nand_base.c.
