mtd: nand: refactor chip->block_markbad interface
The chip->block_markbad pointer should really only be responsible for writing a bad block marker for new bad blocks. It should not take care of BBT-related functionality, nor should it handle bookkeeping of bad block stats. This patch refactors the 3 users of the block_markbad interface (plus the default nand_base implementation) so that the common code is kept in nand_block_markbad_lowlevel(). It removes some inconsistencies between the various implementations and should allow for more centralized improvements in the future. Because gpmi-nand no longer needs the nand_update_bbt() function, let's stop exporting it as well.
