Here are some development updates for the Synopsis Designware HDMI driver,
which clean up some of the code, and start preparing to add audio support
to the driver.  This series of patches are based on a couple of dependent
commits from the ALSA tree.

Briefly, the updates are:
- move comments which should have moved with the phy values to the IMX
  part of the driver.
- clean up the phy configuration: to all lookups before starting to
  program the phy.
- clean up the HDMI clock regenerator code
- use the drm_hdmi_avi_infoframe_from_display_mode() helper which allows
  the code to be subsequently simplified
- remove the unused 'regmap' pointer in struct dw_hdmi
- use the bridge drm device rather than the connector (we're the bridge
  code)
- remove private hsync/vsync/interlaced flags, getting them from the
  DRM mode structure instead.
- implement interface functions to support audio - setting the audio
  sample rate, and enabling the audio clocks.
- removal of broken pixel repetition support
- cleanup DVI vs HDMI sink handling
- enable audio only if connected device supports audio
- avoid double-enabling bridge in the sink path (once in mode_set, and
  again in commit)
- rename mis-named dw_hdmi_phy_enable_power()
- fix bridge enable/disable handing, so a plug-in event doesn't
  reconfigure the bridge if DRM has disabled the output
- fix from Vladimir Zapolskiy for the I2CM_ADDRESS macro name

These are primerily preparitory patches for the AHB audio driver and
the I2S audio driver (from Rockchip) for this IP.
