qemu-ppce500: Add support for 64bit CCSR map
QEMU 2.3 changes the address layout of the CCSR map in the PV ppce500 machine
to reside in higher address space.
Unfortunately, this exposed a glitch in u-boot for ppce500: While providing
a function to dynamically evaluate the CCSR region's position in physical
address space, we never used it. Plus we forgot to support 64bit physical
addresses.
This patch fixes that mishap, making u-boot work fine with latest QEMU again.
