This means that the FLL won't ever get powered off when it goes idle. While it's not going to be such an issue on a board like this as it is a reference design it's likely people will lift the code into places where it does matter so it'd be good to get such support into the driver.

There's no need to explicitly enable pins that aren't being actively managed - the default is for all pins to be enabled.
- snd_soc_dapm_sync(dapm);
Core should be doing this automatically for you these days, on the other hand this does no harm.
