- Improved HDMI and Mixer drivers

Browse Source 
. It moves mode setup and plane update code to commit
     like other CRTC drivers
   . It makes mode commit to be called in enable callback only one time
   . some cleanup and fixup to HDMI and Mixer drivers.
   . It adds 1024x768, 1280x1024 and 1366x768 modes support
 - Added HDMI audio interface driver
   . As of now, HDMI audio worked on boards with external audio codec connected
     in parallel with the HDMI audio transmitter's I2S interface.
     This patch is required to support HDMI audio properly.
