drm/i915/mtl: Fix bcs default context
Commit 0d0e7d1eea9e ("drm/i915/mtl: Define engine context layouts")
added the engine context for Meteor Lake. In a second revision of the
patch it was believed the xcs offsets were wrong due to a tagging
issue in the spec. The first version was actually correct, as shown
by the intel_lrc_live_selftests/live_lrc_layout test:
i915: Running gt_lrc
i915: Running intel_lrc_live_selftests/live_lrc_layout
bcs0: LRI command mismatch at dword 1, expected 1108101d found 11081019
[drm:drm_helper_probe_single_connector_modes [drm_kms_helper]] [CONNECTOR:236:DP-1] disconnected
bcs0: HW register image:
[0000] 00000000 1108101d 00022244 ffff0008 00022034 00000088 00022030 00000088
...
bcs0: SW register image:
[0000] 00000000 11081019 00022244 00090009 00022034 00000000 00022030 00000000
The difference in the 2 additional dwords (0x1d vs 0x19) are the offsets
0x120 / 0x124 that are indeed part of the context image.
