CCing in Takashi since this is generic AC'97 stuff.

So, I'd kind of expect some sort of interaction with gpiolib somewhere if we do support GPIOs (I know the WM97xx custom stuff doesn't currently use GPIOs but...).
If I ever get access to the testhardware again, I'll implement it in the wm97xx core.
