dt-bindings: mfd: axp20x: Introduce bindings for AXP813 



The X-Powers AXP813 is a PMIC designed to be paired with Allwinner's
A83T SoC. There is also an AXP818, which is paired with the H8 SoC.

The two models seem to be identical, apart from the external markings.

This patch introduces the basic mfd and regulator bindings for the
AXP813.

The AXP813 is 2 chips packaged into 1. The 2 chips do not share anything

other than the packaging. Pins are routed separately. As such they should

be treated as separate entities. The other half is an AC100 RTC/codec

combo chip. Please see ./ac100.txt for its bindings.
