hal: Add change to fix speaker and headphone concurrency.
After the device switch from headset to the speaker, lag in playback
was observed.
The issue was seen because both the speaker and headphone was
configured using the native clock.
Add change to configure headphone to 48Khz sample rate before enabling
the use case on speaker.
