Added a PIXIS_BASE_PHYS for use as the physical address and maintain
PIXIS_BASE as the virtual address of the PIXIS fpga registers.
This allows us to deal with 36-bit phys on these boards in the future.

- Move the TLB entry of PIXIS_BASE from TLB0 to TLB1[8], because in CAMP mode,
all the TLB0 entries will be invalidated after cpu1 brings up kernel, thus cpu0
can not access PIXIS_BASE anymore (any access will cause DataTLBError exception)
- Set CONFIG_SYS_DDR_TLB_START to 9 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.

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.
