This series adds support for the HDMI output on the msm8974 platform. It
was tested on the apq8074 dragonboard device.

I'm sending this as an RFC for two reasons:
- The series depends on the other patchset ([1]), which got no feedback
  yet.
- I'm looking at refactoring the HDMI PHY support. I tink it makes
  little sense to land the PHY driver when we know that it is going to
  be reworked during the same development cycle.
