devfreq: update target frequency in cdspl3 governor start

Browse Source 
Trigger an update devfreq to reflect the desired target frequency
when cdspl3 governor is selected for a device. This is to avoid
running with a target frequency set by a different governor before
 cdspl3 governor gets L3 frequency request from CDSP.
