Weird. `git cherry-pick -x b17ef04bf3a4346d66404454d6a646343ddc9749`
worked fine here and we tested that.
Oh, I see, there is an unused variable warning in the cherry-pick
depending on the config. That must have been what failed. Attached
patch should resolve that. Sorry for the confusion.

Subject: [PATCH] drm/amd/display: Pass pwrseq inst for backlight and ABM
[Why]
OTG inst and pwrseq inst mapping is not align therefore we cannot use
otg_inst as pwrseq inst to get DCIO register.
[How]
1. Pass the correct pwrseq instance to dmub when set abm pipe.
2. LVTMA control index change from panel_inst to pwrseq_inst.
Fix unused variable warning in 6.6 (Alex).
