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. Signed-off-by: Tom Rini <trini@ti.com>
