[201/262] drm/radeon: set hpd polarity at init time so hotplug detect works

[Greg KH]

3.0-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Jerome Glisse <jglisse@xxxxxxxxxx>

commit 8ab250d4484b72ccc78e34276c5ffa84c1d41303 upstream.

Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up at module init so first hotplug works
reliably no matter what is the initial set of connector.
