drm/i915/bdw: make sure south port interrupts are enabled properly v2drm-intel-fixes-2014-01-13
We were apparently relying on the defaults on BDW, which resulted in no
hotplug or AUX interrupts. So be sure to call the ibx_irq_preinstall to
enable all interrupts.
v2: use preinstall instead of redundant SDIER write
