I'm actually not sure about these. In retrospect the RK_GPIOx -> x defines do 
not provide any additional value compared to just having the actual value in 
the pinctrl-nodes, so we phased them out largely for the rk3288 boards.

While looking through some boards, I saw that some slipped in for stuff that 
gets copy'n'paste treatment most of the time, but generally we're only using 
the real numbers on boards - and I'd like to keep it that way and phase out 
the RK_GPIOx constants in new boards.
