Since boards like PB11MPCore have 512MB of RAM and 128MB of flash, the
virtual space is short on vmalloc memory and mapping the flash fails.
This patch changes the IO_ADDRESS so that static mappings start at
0xfc000000 and moves the PCI virtual addresses higher up. The new
VMALLOC_END is set to 0xf8000000 (512MB higher than the old value).
