Move the XHCI PCI device base up in the virtual address space. This fixes initialization failure observed with 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. This is still enough for the XHCI PCI device.

This fixes the issue observed on ARM 32bit after upgrading the RPi4 firmware files, described some time ago here: https://lists.denx.de/pipermail/u-boot/2021-February/442317.html
