agp: add chipset flushing support to AGP interface
This bumps the AGP interface to 0.103. Certain Intel chipsets contains a global write buffer, and this can require flushing from the drm or X.org to make sure all data has hit RAM before initiating a GPU transfer, due to a lack of coherency with the integrated graphics device and this buffer. This just adds generic support to the AGP interfaces, a follow-on patch will add support to the Intel driver to use this interface. Signed-off-by: Dave Airlie <airlied@redhat.com>
