[src/riastradh-drm2]: src/sys/external/bsd/drm2/dist/include/drm Add drm_io_m...

description:
Add drm_io_mapping_create_wc to drmP.h.
Linux's io_mapping_create_wc just takes a bus address and a size, but
we need to pass along extra information, namely the bus space tag,
which we shall pass via a struct drm_device.
