The TWL4030 is actually only ever populated from the device tree,
so we can just pass the right device and headphone jack GPIO name
to snd_soc_jack_add_gpios() and it will pick the right GPIO right
from the device tree.
The platform data patch is unused (no in-tree users of the pdata
method) but these can use GPIO descriptor tables rather than global
GPIO numbers if they need this.
