[RFC PATCH 09/17] pinctrl: sunxi: add Allwinner D1 pinctrl description

Apart from using the new pinctrl MMIO register layout, the Allwinner D1
and related SoCs still need to usual set of mux values hardcoded in
U-Boot's pinctrl driver.
Add the values we need so far to this list, so that DM based drivers
will just work without further ado.
