For common arm zImage existing nand header file in platform specific location was moved to generic platform data location, but it contained more than platform data, remove it. New local header has been created for exposing functions. Also move gpmc-nand platform data to platform header meant for nand from gpmc header file Signed-off-by: Afzal Mohammed <afzal@ti.com>
