The DSP in the CA0132 codec adds a variable latency to audio depending
on what processing is being done. Add a new patch op to return that
latency for capture and playback streams. The latency is determined
by which blocks are enabled and knowing how much latency is added by
each block.

Thanks, applied.
This conflicts with the audio timestamp stuff I contributed last year.
If the hardware supports a WALLCLK, and HDA does, the timestamp is just
a read of the counter plus a translation to ns. If it doesn't, the
timestamp corresponds to the delay. If you modify the definition of the
delay then the timestamp will be off on some platforms.
