[RFC PATCH v1 0/3] drm/msm: add support for HDMI on msm8974

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.
