rpi4: add a mapping for the PCIe XHCI controller MMIO registers (ARM 32bit)
Create a non-cacheable mapping for the 0x600000000 physical memory region,
where MMIO registers for the PCIe XHCI controller are instantiated by the
PCIe bridge. Due to 32bit limit in the CPU virtual address space in ARM
32bit mode, this region is mapped at 0xff800000 CPU virtual address.
