Subject: drm/tegra: sor: Use correct I/O pad for DP
Git-commit: d23691f647855ff765c67d281ec73c59104d9eb1
Patch-mainline: v5.5-rc1
References: bsc#1152472

The correct I/O pad needs to be powered up before DP can be used. Make
sure the correct default is set for Tegra generations where the I/O pad
cannot be derived from the SOR instance.
