pinctrl: sunxi: add Allwinner A100/A133 pinctrl description
The Allwinner A100 SoC has been around for a while, and has now seemingly been replaced with its close sibling A133. Add the required mapping between the pinmux group strings and their respective mux value, as far as used by U-Boot proper. Linux has some basic (clock and pinctrl) support for a while, so we can build on the names already used there.
