[PATCH 1/6] mfd: axp20x: Add AXP223 to list of supported PMICs in DT bindings

[Chen-Yu Tsai <wens-jdAy2FN1RRM@public.gmane.org>]

The AXP223 is a new PMIC commonly paired with Allwinner A23/A33 SoCs.
It is functionally identical to AXP221; only the regulator default
voltage/status and the external host interface are different.
