OMAP3 SPL: Add identify_nand_chip function
A number of boards are populated with a PoP chip for both DDR and NAND
memory. Other boards may simply use this as an easy way to identify
board revs. So we provide a function that can be called early to reset
the NAND chip and return the result of NAND_CMD_READID. All of this
code is put into spl_id_nand.c and controlled via CONFIG_SPL_OMAP3_ID_NAND.
