drm/i915: More PVC+DG2 workarounds
A new PVC+DG2 workaround has appeared recently:
- Wa_16015675438
And a couple existing DG2 workarounds have been extended to PVC:
- Wa_14015795083
- Wa_18018781329
Note that Wa_16015675438 asks us to program a register that is in the
0x2xxx range typically associated with the RCS engine, even though PVC
does not have an RCS. By default the GuC will think we've made a
mistake and throw an exception when it sees this register on a CCS
engine's save/restore list, so we need to pass an extra GuC control flag
to tell it that this is expected and not a problem.
