Like dp_out, we should have defined edp_out in sc7280.dtsi so we don't
need to do this in the board files.
Like dp_hot_plug_det, we should define edp_hot_plug_det in
sc7280.dtsi.
We should set the default pinctrl for edp_hot_plug_det in
sc7280.dtsi. NOTE: this is _unlike_ the dp_hot_plug_det. It is
reasonable that in some boards the dedicated DP Hot Plug Detect will
not be hooked up in favor of Type C mechanisms. This is unlike eDP
where the Hot Plug Detect line (which functions as "panel ready" in
eDP) is highly likely to be used by boards.
