mpc8641: Support 36-bit physical addressing
This patch creates a memory map with all the devices
in 36-bit physical space, in addition to the 32-bit map.
The CCSR relocation is moved (again, sorry) to
allow for the physical address to be 36 bits - this
requires translation to be enabled. With 36-bit physical
addressing enabled, we are no longer running with VA=PA
translations. This means we have to distinguish between
the two in the config file. The existing region name is
used to indicate the virtual address, and a _PHYS variety
is created to represent the physical address.
Large physical addressing is not enabled by default.
Set CONFIG_PHYS_64BIT in the config file to turn this on.
