drm/i915/icl: WaL3BankAddressHashing
Revert to an L3 non-hash model, for performance reasons.
v2:
- Place the WA name above the actual change
- Improve the register naming
v3:
- Rebased
- Renamed to Wa_1604223664
v4: Rebased on top of the WA refactoring
v5:
- Added References (Mika)
- Fixed wrong mask and value (Mika)
- Do not apply together with another WA for the same
register (not worth the hassle)
v6:
- Rebased
- C, not lisp (Chris)
References: HSDES#1604223664
