This patch adds two new test topologies. One is for testing ASRC
timestamp retrieving from HDA and one for WM8804 slave SSP interface
for APL. It is useful with UP^2 board with HiFiBerry Digi+ SPDIF
interface.
The asynchronous mode token is switched on in ASRC capture and
playback pipelines. It switches on DAI skew tracking feature
in ASRC.
