Chris Wilson 3497971a71 agp/intel: Flush chipset writes after updating a single PTE 
After we update one PTE for a page, the caller expects to be able to
immediately use that through a GGTT read/write. To comply with the
callers expectations we therefore need to flush the chipset buffers
before returning.
