mfd: Implement runtime PM for WM8994 core driver

Allow the WM8994 to completely power off, including disabling the LDOs
if they are software controlled, when it goes idle. The CODEC subdevice
controls activity for the MFD as a whole.

If the GPIOs need to be used while the device is active runtime PM
should be disabled for the device by machine specific code.
