The GPIOs belong to a submodule of TWL4030, but they are configured
using standard gpiolib.

About adding GPIO functionality to jack detection, if the right
place to request GPIOs and set its data direction is in board files
(arch/*/mach-*/board-*.c), then there won't be much to do in jack
code, only the irq request. Unless we move request and data direction
setting to jack detection layer.
