mtd: nand: Make flags for bad block marker position more granular
To be able to check and set bad block markers in the first and
second page of a block independently of each other, we create
separate flags for both cases.
Previously NAND_BBM_SECONDPAGE meant, that both, the first and the
second page were used. With this patch NAND_BBM_FIRSTPAGE stands for
using the first page and NAND_BBM_SECONDPAGE for using the second
page.
This patch is only for preparation of subsequent changes and does
not implement the logic to actually handle both flags separately.
