Correct FM sequence in turn on and audio focus loss/gain cases for wcn3990

The FM sequence is different for wcn3990 compared to older targets ->
When enabling FM ->
1. Enable Cherokee SB slave block.
2. From FM audio driver configure SB master and port.
3. Enable FM radio on Cherokee.

When audio focus changes from FM to A2DP ->
1. FM audio driver disable/resets SB port.
2. Cherokee FM radio is shutdown (SB slave port is left enabled).

When turning off FM ->
1. FM audio driver disables/shuts down SB port.
2. Cherokee FM shuts down both FM radio and SB slave block.
