drm/i915/perf: Use GTT when saving/restoring engine GPR
commit aee62e02c48bd62b9b07f5e297ecfc9aaa964937 upstream.
MI_STORE_REGISTER_MEM and MI_LOAD_REGISTER_MEM need to know which
translation to use when saving restoring the engine general purpose
registers to and from the GT scratch. Since GT scratch is mapped to
ggtt, we need to set an additional bit in the command to use GTT.
Fixes: daed3e44396d17 ("drm/i915/perf: implement active wait for noa configurations")
