[Intel-gfx] [PATCH v2 13/13] drm/i915/xehpsdv: Move render/compute engine reset domains related workarounds

[Matt Roper]

From: Srinivasan Shanmugam <srinivasan.s at intel.com>

Registers that exist in the shared render/compute reset domain need to
be placed on an engine workaround list to ensure that they are properly
re-applied whenever an RCS or CCS engine is reset.  We have a number of
workarounds (updating registers MLTICTXCTL, L3SQCREG1_CCS0,
GEN12_MERT_MOD_CTRL, and GEN12_GAMCNTRL_CTRL) that are incorrectly
implemented on the 'gt' workaround list and need to be moved
accordingly.
