drm/radeon/kms: set HPD polarity in hpd_init()
commit 64912e997f0fe13512e4c7b90e4f7c11cb922ab5 upstream.
Polarity needs to be set accordingly to connector status (connected
or disconnected). Set it up in hpd_init() so first hotplug works
reliably no matter what is the initial set of connector. hpd_init()
also covers resume so HPD will work correctly after resume as well.
