drm/radeon/kms: simplify hotplug handler logic
In the hotplug handler, just use the drm dpms functions. If the monitor is plugged in, turn it on, if it's not, turn it off. This also reduces power usage by turning off the encoder and crtc when the monitor is unplugged. Signed-off-by: Alex Deucher <alexdeucher@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
