Use pmap_mapdev()/pmap_unmapdev() to map device memory instead of using
AcpiOsMapMemory()/AcpiOsUnmapMemory() (-> pmap_mapbios()/pmap_unmapbios())
for AcpiOsReadMemory() and AcpiOsWriteMemory(). Although they do not sound
too obvious, these functions are exclusively used to access memory mapped
IO in ACPICA.
