Registers that belong to the shared render/compute reset domain need to be placed on an engine workaround list to ensure that they are properly re-applied whenever any RCS or CCS engine is reset, even if the registers do not belong to a specific engine's MMIO range. We have a number of workarounds today that are incorrectly implemented on the 'gt' workaround list and need to be moved accordingly. We also have one workaround (Wa_22012532006) that is incorrectly implemented on the context workaround list, even though the register it is adjusting is not part of the RCS engine's context image; it must also be moved. We'll have some workaround refactoring coming in the near future that deals with registers in the reset domain in a more clear way. But in the meantime, we should just move these workarounds to rcs_engine_wa_init() to place them on the RCS engine's workaround list. All production DG2 platforms will have an RCS engine (it's never fused off) so these registers will be properly restored after a domain reset triggered via an RCS engine _or_ a CCS engine.
