drm/i915/mtl: Define MOCS and PAT tables for MTL
On MTL, GT can no longer allocate on LLC - only the CPU can.
This, along with programming new register bits that MTL
requires calls for a MOCS/PAT table update.
Also the PAT index registers are multicasted for primary GT,
and there is an address jump from index 7 to 8. This patch
makes sure that these registers are programmed in the proper
way.
