ASoC: msm: Migrate audio drivers to new clock apis.

Use the split clock APIs to do low latency actions (enable/disable)
frequently.  Use the high latency functions (prepare/unprepare)
sparingly to help performance.
Using these split apis instead of the 2 current APIs, allows the
clock driver to perform the slow steps with a mutex lock held and
removes the need to busy wait for the slow steps to finish.
