Bug description:
  [Impact]
  Blank DP display after S3 on Intel GFX in ICL PCH desktop.

  [Fix]
  Use proper IRQ setup so the system in question can detect HPD after S3.

  [Test]
  Suspend and resume the system. No picture on DP display.
  With the patch applied, DP display works as expected.

  [Where problems could occur]
  It changes how the Intel GFX setup its HPD IRQ, so hotplug detection
  will be affected. This change is limited to ICL PCH.

  This is the second patch of "drm/i915/gen9bc: Handle TGP PCH during
  suspend/resume", but somehow it was omitted.
