On systems with caches enabled, NAND I/O may need to flush/invalidate the cache during read/write operations. For this to work correctly, all buffers must be cache-aligned. Fix nand_verify*() to allocate aligned buffers.
This prevents cache alignment warnings from being spewed when using U-Boot to write an updated version of itself to flash on NVIDIA Tegra Seaboard (after perturbation of stack/data layout in current u-boot-dm/next branch).
I have validatd (executed) nand_verify(), but I don't think I've executed nand_verify_page_oob(); testing of that would be useful.
