[u-boot][PATCH 03/14] mtd: rawnand: omap_gpmc: Fix build warning on 64-bit platforms

[Roger Quadros <rogerq@kernel.org>]

Pointer size cannot be assumed to be 32-bit, so use
use uintptr_t instead of uint32_t.

Fixes the below build warning on 64-bit builds.

drivers/mtd/nand/raw/omap_gpmc.c:439:10: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
  head = ((uint32_t) buf) % 4;
