Haiying Wang c013b74975 NAND: Add support for MPC8572DS board
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.
