mtd: fsl_elbc_nand: remove unnecessary badblock_pattern
Since the introduction of nand_create_default_bbt_descr() (now known as
nand_create_badblock_pattern()) in
commit 58373ff0afff4cc8ac40608872995f4d87eb72ec
nand_chip.badblock_pattern will be dynamically calculated to the same
1-byte-length pattern that is required by fsl_elbc_nand. This custom
badblock_pattern is no longer needed, then, and its removal may help
facilitate further nand_bbt.c/nand_base.c cleanup in the future (one
down, many to go?)
Anyway, with nand_bbt.c fixed, this effectively reverts:
commit 452db2724351ff3d9416a183a7955e00ab4e6ab4
[MTD] [NAND] fsl_elbc_nand: fix OOB workability for large page NAND chips
