drm/i915: SDVO hotplug have different interrupt status bits for i915/i965/g4x
commit 084b612ecf8e59973576b2f644e6949609c79375 upstream.
Note that gen3 is the only platform where we've got the bit
definitions right, hence the workaround of disabling sdvo hotplug
support on i945g/gm is not due to misdiagnosis of broken hotplug irq
handling ...

[danvet: add some blurb about sdvo hotplug fail on i945g/gm I've
wondered about while reviewing.]

[bwh: Backported to 3.2:
- Adjust context
- Handle all three cases in i915_driver_irq_postinstall() as there
are not separate functions for gen3 and gen4+
- Carry on using IS_SDVOB() in intel_sdvo_init()]
