drm/amd/display: Pass pwrseq inst for backlight and ABM

2024-01-20T10:51:48+00:00

commit b17ef04bf3a4346d66404454d6a646343ddc9749 upstream. [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.
