audio: Add a separate HAL for HDMI audio

Creating an audio HAL for HDMI because:

  * The HDMI card is already a separate card from
    the OMAP ABE audio.

  * The needs of HDMI are getting more specialized
    (e.g. things like multichannel audio, bitstream
    audio, etc.)

  * Things in the OMAP ABE HAL are getting a bit
    cramped and complex, and it would be better to
    reduce the complexity rather than add to it.

This version is provides the same functionality as audio_hw.c

audio: hdmi: add dynamic multichannel support

This patch parses the HDMI EDID to find the capabilites of the sink
device.  It communicates this information to Android so that it can
make the proper decisions about routing multichannel streams.

When parsing the EDID we look for:

  * Audio Bit (whether or not sink supports audio)

  * Speaker Allocation Data Block (if any), which
    declares which speakers are attached to the sink.

  * Audio Data Allocation Block (if any), which
    declares extended capabilities not implied by the
    Audio Bit.

The speaker allocation block is parsed to see which channel profiles
it supports (stereo, quad, surround, 5.1, and 7.1).
