Wei Liu de4ff39f4d pci: align VFIO MMIO mmap to a huge page boundary ...

mmap(NULL, ...) only guarantees page-sized alignment, so the device
MMIO regions mapped for VFIO passthrough were not necessarily aligned
on a huge page boundary and thus could not take fast paths in the
kernel.

Align the address to the largest possible size. This allows VFIO to take
fast paths when walking the page table.
