[Intel-gfx] [PATCH v.2 08/12] DRM/i915: Treat hpd_irq_setup() for ironake and older generations the same way.

[Egbert Eich]

When switching to enabling HPD IRQs only for lines where needed and supported
this will ensure that the right lines will be enabled on all generations when
intel_hpd_init() is called.
