[PATCH 0/6] pinctrl: sunxi: Allwinner D1/D1s support

This series adds pinctrl support for the Allwinner D1/D1s SoCs. First,
it updates the I/O bias code to support the new mode found on the D1/D1s
(as well as some existing SoCs). Then it refactors the driver to support
the new register layout found on the D1/D1s. Finally, it adds the new
driver.

The code size impact of the dynamic register layout ends up being just
over 100 bytes:

   text    data     bss     dec     hex filename
  11293     564       0   11857    2e51 pinctrl-sunxi.o (patch 3)
  11405     564       0   11969    2ec1 pinctrl-sunxi.o (patch 6)

This series was tested on A64, H6, and D1.
