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.

The 8544 DS doesn't have any cacheable Local Bus memories set up. By mapping
space for some anyway, we were allowing speculative loads into unmapped space,
which would cause an exception (annoying, even if ultimately harmless).
Removing LBC_CACHE_BASE, and using LBC_NONCACHE_BASE for the LBC LAW solves the
problem.

With the new LAW interface (set_next_law) we can move to letting the
system allocate which LAWs are used for what purpose. This makes life
a bit easier going forward with the new DDR code.

Move the initialization of the LAWs into C code and provide an API
to allow modification of LAWs after init.
Board code is responsible to provide a law_table and num_law_entries.
We should be able to use the same code on 86xx as well.
