powerpc 86xx: Handle CCSR relocation earlier
Currently, the CCSR gets relocated while translation is
enabled, meaning we need 2 BAT translations to get to both the
old location and the new location. Also, the DEFAULT
CCSR location has a dependency on the BAT that maps the
FLASH region. Moving the relocation removes this unnecessary
dependency. This makes it easier and more intutive to
modify the board's memory map.
Swap BATs 3 and 4 on 8610 so that all 86xx boards use the same
BAT for CCSR space.
