To their rightful place inside intel_workarounds.c
TODO: Notice that we are leaving WaProgramL3SqcReg1Default (and the
associated WaTempDisableDOPClkGating) behind because it requires extra
careful reviewing. We'll deal with it in a separate patch.
v2: Classify WaDisableCSUnitClockGating and WaDisableSDEUnitClockGating
as GT WAs
