[PATCH 7/8] xhci: translate virtual addresses into the bus's address space

So far we've been content with passing physical addresses when configuring memory addresses into XHCI controllers, but not all platforms have buses with transparent mappings. Specifically the Raspberry Pi 4 might introduce an offset to memory accesses incoming from its PCIe port. Introduce
