[PATCH 6.7 12/28] drm/amd/display: Pass pwrseq inst for backlight and ABM

6.7-stable review patch. If anyone has any objections, please let me know.

------------------

From: Lewis Huang lewis.huang@amd.com

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.
