ASoC: topology: Fix bclk and fsync inversion in set_link_hw_format()

Browse source 
The values of bclk and fsync are inverted WRT the codec. But the existing
solution already works for Broadwell, see the alsa-lib config:

`alsa-lib/src/conf/topology/broadwell/broadwell.conf`

This commit provides the backwards-compatible solution to fix this misuse.
This commit goes in pair with the corresponding patch for linux.
