radeon: deal with connectors sourced to the same encoder
Some systems have multiple connectors connected to the
same encoder; e.g., DVI and HDMI connected to the same
encoder with the same ddc line. Since we expose
connectors as xrandr outputs, randr treats them separately
which results in it trying to source the same encoder to
different crtcs. If we have an HDMI and DVI-D port on the
same encoder, pick the one to be considered connected
based on the edid (HDMI if edid indicates HDMI, DVI
otherwise). Also, don't turn off (dpms) encoders that are
shared.
Fixes fdo bug 21767.
