gpio: drop gpio_set_high/low from vtable, and from pc8736x_gpio

1 - drops gpio_set_high, gpio_set_low from the nsc_gpio_ops vtable. While we can't drop them from scx200_gpio (or can we?), we dont need them for new users of the exported vtable; gpio_set(1), gpio_set(0) work fine. v2 also deletes those functions from pc8736x_gpio, fixing the unused warnings. scx200_gpio doesnt need this, its functions are defined in the header file.
