I appreciate that the function is the same for each pin but this still
looks odd. Perhaps just #define SUNXI_GPFx_SDC0 and use that?
I did something similar yesterday and just opencoded the calls.

I was wondering about these -- do these matter even when the PIN is
configured for a specific function and not as a GPIO?
(same comments for all the others)
