qemu-ppce500: Add support for 64bit CCSR map

Browse Source 
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.
