drm/i915/tv: Use polling rather than interrupt-based hotplug
The documentation recommends that we should use a polling method for TV
detection as this is more power efficient than the interrupt based
mechanism (as the encoder can be completely switched off). A secondary
effect is that leaving the hotplug enabled seems to be causing pipe
underruns as reported by Hugh Dickins on his Crestline.

[This is a candidate for stable, but needs minor porting to 2.6.37]
