mfd: provide and use setup hook for tc6393xb
Instead of using bitfields for initial gpio setup, provide generic setup/teardown hooks that can be used to set the gpio states, register child devices, etc. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Signed-off-by: Samuel Ortiz <sameo@openedhand.com>
