[Mesa-dev] [PATCH 1/2] [v3] i965/skl: Add GT4 PCI IDs

[Ben Widawsky]

Like other gen8+ hardware, the hardware automatically scales up thread counts
and URB sizes, so there is no need to do anything but add the PCI IDs.

FINISHME: This patch still needs testing before merge.

v2: Remove the PCI ID removal. That should be done as part of the next patch.

v3: Update the wm thread count to support GT4.
