fsl_ifs_spl.c reads data from NAND and store at a memory location in raw mode. It does not used MTD layer. To read env variable from NAND MTD layer read/write required.

Hence, add mtd_block_isbad & nand_read_skip_bad function required during env variable read.

Also, avoid nand_info during env read for SPL
