Subject: [PATCH 46/90] ARM: dts: sunxi: Add AXP221 and AXP809 GPIO nodes

These PMICs each have two GPIO pins, and are supported by the axp_gpio
driver. In order to convert the axp_gpio driver to probe using the
device tree, the corresponding device tree nodes must be present. Add
them, following the same binding as the AXP209 and AXP813.
