Implement a subset of known HardWare WorkArounds for gen 9.
v1: Make gen 9 common patchset, remove non-common w/a's, tidy up
patch names, tidy up register names (Req: Damien Lespiau).
Removed invalid WA (Found by
Arun Siluvery). Removed WaSetHdcUnitClockGatingDisableInUcgctl6
until feature exists (Found by Jeff Mcgee).
v2: Added stepping check for WAs. Removed WaDisableThreadStallDopClockGating
as not SKL WA (Found by Damien Lespiau). Don't add WaHdcDisableFetchWhenMasked.
Rebased as necessary.
v3: Use existing revision id
v4: Rebase to Intel DRM nightly. Moved register bitmap to correct patch.
