[u-boot][PATCH v2 2/8] mtd: rawnand: nand_base: Allow base driver to be used in SPL without nand_bbt

[Roger Quadros]

nand_bbt.c is not being built with the nand_base driver during SPL
build. This results in build failures if we try to access any nand_bbt
related functions.

Don't use any nand_bbt functions for SPL build.
