rockchip: Add gpio_set() function

The <gpio.h> API is supposed to include a gpio_set() function that just
toggles the state of a GPIO already configured as an output, even though
we rarely need it since gpio_output() can already be used to initialze a
GPIO to a default value while configuring it as an output. This function
was forgotten on Rockchip, so this patch adds it now.
