Ben Skeggs b29caa5885 drm/nouveau: add overscan compensation connector properties
Exposes the same connector properties as the Radeon implementation, however
their behaviour isn't exactly the same.  The primary difference being that
unless both hborder/vborder have been defined by the user, the driver will
keep the aspect ratio of the overscanned area the same as the mode the
display is programmed for.

Enabled for digital outputs on GeForce 8 and up, excluding GF119.
