[101/119] agp/intel: new host bridge support

[Greg KH]

2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Zhenyu Wang <zhenyuw@xxxxxxxxxxxxxxx>

commit 9cf1e35cb025eaa52dde37df38e2750b6adb1620 upstream.

Add new CPU host bridge id, needed for support Ironlake graphics
device with it. No change for graphics device itself, so no need to
update drm/i915.
