CRAS: Use the hardware timestamp with available/used frames.
The ALSA device drivers can provide a timestamp associated with
the buffer read-pointer. This can be use to more accurately guage
the time that the next buffer is required.
Enable this functionality only when supported ALSA in the running
kernel.
BUG=None
TEST=Unit tests pass.
Verified on Samus (on kernel v3.14).
Verified on new device (kernel v3.18 - htimestamp enabled).
Verified a bluetooth device.
Verified a USB device.
