This patch is proposed as a result of a previous discussion related to
include audio support in the DSS device driver

At the moment, this is intended to cover display technologies with audio based
on CEA-861 and IEC-60958, such as HDMI and DisplayPort. However, provisions are
made to make it extensible (see below).

These are the changes with respect to v2:

* A new enum and field is added to DSS to help implementations of the interface
  to keep track of the audio state.

These are the changes with respect to v1:

* The audio_enable and audio_start functions were split into enable/disable
  and  start/stop respectively to improve readability.
* Comments were added on whether the DSS audio functions may sleep.
* In order to make the audio configuration parameters extensible, a
  struct omap_dss_audio is defined. This helps to easily add more config
  parameters in the future if/when required (e.g., speaker order configuration).
