Add a separate output for VGA connectors with BMC support. Convert code for server models. Keep the original VGA for regular G200 models. The VGA-BMC output either reports the connected VGA display or, if that is not available, the BMC. Makes the BMC connector obsolete, so remove it. The benefit of the VGA-BMC connector is that is works with any userspace. Most userspace compositors have problems configuring the current BMC connector. The BMC connector is now gone and only a VGA connector is present. A different approach to removing the BMC connector has been tried in [1]. The new series also picks up an idea from an older series, [2] where BMC support is entirely transparent to the CRTC.
