Subject: drm/i915/gen12: Update shadowed register table
Git-commit: 5798a769d6f5be656638c5e6e0cd5c4f155a2fb5
Patch-mainline: v5.16-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
The bspec lists many shadowed registers (i.e., registers for which we
don't need to grab forcewake when writing) that we weren't tracking in
the driver. Although we may not actually use all of these registers
right now, it's best to just match the bspec list exactly.
Note that the bspec also lists registers that are shadowed for various
HW-internal accesses; we can ignore those and just list the ones that
are shadowed for accesses from the IA/CPU.
Bspec: 52077
