drm/radeon/kms: enable underscan option for digital connectors
This connector attribute allows you to enable or disable underscan
on a digital output to compensate for panels that automatically
overscan (e.g., many HDMI TVs). Valid values for the attribute are:
off - forces underscan off
on - forces underscan on
auto - enables underscan if an HDMI TV is connected, off otherwise
default value is auto.
