pinctrl: sunxi: add Allwinner A523 pinctrl description

Browse Source 
The new DT pinctrl binding would allow us to read the pinmux values from
the DT, but it is actually easier to just continue with hardcoding the
mux values in the driver, and matching them against the "function" name.

Add the values for the primary and secondary pin controller on the A523.
