ASoC: wm8994: follow AIF clock source changes in MCLK gating
The AIF clock source can be changed by configure_aif_clock() while the
AIF clock is running, for example the Midas machine driver switches
AIF1 between MCLK2 and FLL1 while AIF1CLK is kept enabled for jack
detection. aif_mclk_set() only enables the MCLK selected at the time
the AIF clock is turned on, so an MCLK selected later this way is never
enabled, and the codec may run from a stopped clock.
Track whether the AIF clock is running and, if so, enable the newly
selected MCLK in configure_aif_clock() before switching to it, then
release the previously enabled one.
