This patch defines 1M TLB&LAW size for NAND on MPC8572DS, assigns
0xffa00000 for CONFIG_SYS_NAND_BASE and adds other NAND supports in
config file.
It also moves environment(CONFIG_ENV_ADDR) outside of u-boot image, to
make room for the increased code size with NAND enabled.

Changing the flash from cacheable to cache-inhibited was taking a significant
amount of time due to the fact that we were iterating over the full 256M of
flash. Instead we can just flush the L1 d-cache and invalidate the i-cache.
