audio_hw: allow to set sound card by properties
To manually specify the audio in and out device nodes, set the
properties like:
Audio in: hal.audio.in=pcmC1D0c
Audio out: hal.audio.out=pcmC1D3p

select_card: only open PCM devices with the same type as requested
Let select_card() only open /dev/snd/pcmCxp for playback and /dev/snd/pcmCxc
for capture device. This way select_card won't try to open a device twice.
In some cases the second query on a playback device(even though
select_card is searching for a capture device) will block inside the
kernel causing audio to stop working.

audio_hw: cache HDMI audio interface
Now we cache the HDMI audio interface as well to avoid misusing them.
We are near to fully support HDMI audio. What missed is the events
to trigger the switching between primary speaker and HDMI.

The change tries to remove the error message:

However, audio_route still doesn't work properly unless

Fix bad sleep time
The bad sleep time occurs when pcm_get_htimestamp() fails, leaving
kernel_frames uninitialized and causing out->cur_write_threshold to be
set to a very large value. The following patch ensures kernel_frames is
initialized to a sane value, it should fix most of the "limiting sleep
time" warnings and stuttering audio caused by sleeping too much.
