omap4460: fix TPS initialization
TPS power IC is controlled using a GPIO (gpio_wk7).
This GPIO should be maintained at logic 1 always. As
such an internal pull-up on this pin will do the job,
driving the GPIO outuput is not needed. This will avoid
the need of using GPIO library in SPL and also may
save some power.
