Log message:
Fill in the bus_dma_sync for intagp to use clflush instead of wbinvd()
if supported.
When we do memory management on intel this would lead to a LOT of
wbinvd() to deal with gpu->cpu incoherency. no one wants that.
Needed for sanity of inteldrm memory management which is coming up next.
