Subject: [PATCH 20/20] chtnau8824: Add a SST define/variable

Add a SST define which gets set to "yes" when using the SST driver
and to "" when not using the SST driver;

And decide if platforms/bytcr/PlatformEnableSeq.conf should be included
or not based on this.

This is a preparation patch for adding SOF support.
