There are 120uF capacitors connected to HP_L and HP_R.  Unfortunately, I
can't quite figure out whether I need platform data or not.

Also, how do I get the platform data to the codec driver?  Do I need to
create some arch code that reads the device tree properties and parses
them into a wm8960_data object, and then (somehow) injects that into the
wm8960 driver?
