drm/i915/pvc: Define MOCS table for PVC
v2 (MattR):
- Clarify comment above RING_CMD_CCTL programming.
- Remove bspec reference from field definition. (Lucas)
- Add WARN if we try to use a (presumably uninitialized) wb_index of 0.
On most platforms 0 is an invalid MOCS entry and even on the ones
where it isn't, it isn't the right setting for wb_index. (Lucas)
