That would be the normal place to control a PLL used to clock the audio
subsystem, yes.  If it's more generally used then it probably ought to
go in the core driver - something along the lines of the clock API would
be useful for arbitration (the clock API itself can't really be used
since it only really works with on-SoC clocks).
