drm/i915: Add port A HPD support for IVB/HSW
As with ILK/SNB wire up the port A HPD on IVB/HSW.
This might be more important on HSW with PSR. BSpec tells us that if the
automagic link training performed by the hardware fails for some reason,
we're going to get a short HPD and are supposed to re-train the link
manyally.
v2: 0 initialize pin_mask/long_mask due to intel_get_hpd_pins() changes
Add a comment about the pulse duration bits being reserved on HSW+
like we have for LPT+ in ibx_hpd_irq_setup()
