pc8736x_gpio needs a real nsc_gpio_ops.gpio_current(), (the previous
just threw a dev_warn). This patch adds that code to read the chip's
current-pin-output-settings, then adds the initialization of the
shadow-regs to them. (the shadow regs are there to preclude the slow
peripheral access needed otherwize)
