Disable a bunch of clock gating disables on IGD_GM, which doesn't need them.
Besides our driver having fallen through to the GM965 path for
RENCLK_GATE_D1, the BIOS was turning some of these on. It may be relevant
for previous platforms as well to zero out the fields that should be zero
in the other registers.
