CRAS: Allow DSP pipeline to change number of channels.
Some new input processing, such as beamforming will reduce the number
of input channels. Change the DSP pipeline to support this.
BUG=none
TEST=play/record audio on Panther.

CRAS: Calculate dsp pipeline delay and add it to the reported latency.
BUG=none
TEST=run loopback_latency test and observed reported latency is closer
to the measured latency by 6ms when drc is used.

CRAS: Move apply_dsp from audio thread.
apply_dsp is a function that only cares about the dsp pipdline, not
the thread. Move it with other pipeline specific code. Thanks
chihchung@ for getting the unit tests to work with this.
BUG=chromium-os:35272
TEST=make check, play/record/unified audio with test client.
