alsatplg allows setting inverted bclk and fsync polarities by setting either bclk_invert or fsync_invert to "true". This patch adds a default parameter in the SSP_CLOCK m4 macro which allows setting inverted bclk and fsync polarities.

The change looks ok, I had a similar fix a long time ago and never upstreamed it... we'll also need to add support for missing Intel quirks that the firmware supports but neither topology or kernel do.
since the patch handling is now mostly on github, would you mind creating a Pull Request here: https://github.com/thesofproject/sof/pulls
Thanks!
