<pre>commit ee435831ec83344dba5ccddd4ffcc6ca95d1cf77

drm/i915/icl: account for context save/restore removed bits
The RS_CTX_ENABLE and CTX_SAVE_INHIBIT bits are not present on ICL
anymore, but we still try to set them and then check them with
GEM_BUG_ON, resulting in a BUG() call. The bug can be reproduced by
igt/drv_selftest/live_hangcheck/others-priority and our CI was able
to catch it.
It is worth noticing that commit 05f0addd9b10 ("drm/i915/icl: Enhanced
execution list support") already tried to avoid the save bits
on ICL, but only inside populate_lr_context().
