topology: set glk kwd pipeline rate to 16kHz
Browse files Browse the repository at this point in the history 
Currently glk kwd pipeline is set to run at 48kHz. This rate is wrong
and will create too big buffers and we will run out of memory. So set
the kwd pipeline rate to 16kHz.

Is this going to be cherry-picked over to the glk stable branch?
