description:
use pci_mapreg_type() instead of assuming PCI_MAPREG_TYPE_MEM.
suggested by riastradh@.

fixes hdaudio on thinkpad P51 where the registers are mapped
over 4GB range.  probably fixes intel X10-based systems that
map hdaudio high as well, but i was able to work around that
in the BIOS.  not so for the P51.

XXX: pullup-7, pullup-8.
