drm/i915: Call encoder hotplug for init and resume cases

Browse source 
For all the encoders, call the hot_plug if it is registered.
This is required for connected boot and resume cases to generate
fake hpd resulting in reading of edid.
Removing the initial sdvo hot_plug call too so that it will be called
just once from this loop.
