From c34175af648b0993f0474fecf015b0f9c125ea37 Mon Sep 17 00:00:00 2001
From: hersen wu <hersenxs.wu@amd.com>

Subject: [PATCH 1150/2940] drm/amd/display: Connect dig_fe to otg directly
 instead of calling bios

[Why] After call bios table crtc_source_select, dal will program fmt
again. The bios table program dig_source_select and other fmt register
for bios usage which is redundancy and uncessary.

[How] Program dig_soruce_select register directly
