pxa3xx_nand: move pxa3xx_nand.h common into plat directory
Since the same nand controller is shared between ARCH_PXA and ARCH_MMP. Move the pxa3xx_nand.h from mach directory to plat directoy. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Cc: David Woodhouse <david.woodhouse@intel.com> Signed-off-by: Eric Miao <eric.y.miao@gmail.com>
