we can get rid of it, if it's controversial.

The only constant that gets used is RK_FUNC_GPIO in 
rockchip_pmx_gpio_set_direction and rockchip_irq_set_type to not have arbitary 
"0"-values when switching to the gpio function.

So it wouldn't be problem to simply keep this constant in the driver itself 
instead of including the dt-binding constants.
