[POWERPC] 4xx: Use machine_device_initcall() for warp_nand
With a multiplatform kernel, once built we always have warp_setup_nand_flash() called and NDFC probed, no matter what machine we actually run on. This potentially can cause problems (such as kernel crash), since NDFC is probed at a warp-predefined address. Using machine_device_initcall() NAND devices are registered if we run on a warp only.
