mfd: axp20x: Add support for AXP813 PMIC
The X-Powers AXP813 PMIC is normally used with Allwinner's A83T SoC. It has the same range of functions as other X-Powers PMICs, such as DC-DC buck converter and linear regulator outputs, AC-IN and VBUS power supplies, power button trigger, GPIOs, ADCs, and a battery charger. Note that the IRQ table given in the datasheet is incorrect: in IRQ enable/status registers 1, there are separate IRQs for ACIN and VBUS, instead of bits [7:5] being the same as bits [4:2]. So it shares the same IRQs as the AXP803, rather than the AXP288. This patch adds basic mfd support for it, with only the power button enabled.
