pinctrl: sunxi: Add support for the Allwinner A523

Browse source

The Allwinner A523 contains pins in 10 out of the 11 possible pin banks;
it just skips port A.
Use the newly introduced DT based pinctrl driver to describe just the
generic pinctrl properties, so advertise the number of pins per bank
and the interrupt capabilities. The actual function/mux assignment is
taken from the devicetree.
