Subject: drm/i915: Parameterize PWRCTX_MAXCNT
Git-commit: cd5d2fdb045fb31a152cbb257e10da78fa4f06ac
Patch-mainline: v5.18-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
Rather than having separate definitions for each engine, create a single
parameterized macro that takes the engine base offset. This will also
ensure we get to the proper offset if we ever need to use these
registers on newer platforms (where the media engine offsets have
changed).
