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).
