The platform claims to have an eDP panel connected, apparently even in hybr=
id
graphics mode when it's not actually in use.  The non-DC code assumes that =
if
there is an eDP panel, it's always connected since it's a non-removable dis=
play
and it shouldn't be present if there isn't one.  Because the driver thinks a
display is connected, the dGPU is kept on.
