ENGR00172342-2 EDID parse audio data blocks
Add functionality to parse Audio Data Blocks from EDID data to
find out what modes of LPCM are suppored by the HDMI sink device.
The parsed settings are saved in the hdmi mfd. The HDMI audio driver
will check the settings when the audio stream is opened and will
then apply appropriate constraints.
If we are unable to read from the EDID, then we default to supporting
Basic Audio as defined by the HDMI specification (stereo, 16 bit,
32KHz, 44.1KHz, 48KHz PCM).
