Move the XHCI PCI device base up in the virtual address space. This fixes
initialization failure observed on newer Raspberry Pi firmware (later
than
63b1922311 ("firmware: arm_loader: Update armstubs with those from
PR 117). It looks that chosing 0xff800000 as the XHCI PCI device base
conflicts with the updated ARM/VideoCore firmware.
This also requires to reduce the size of the mapped PCI device region
from 8MiB to 4MiB to fit into 32bit address space.
