mfd: axp20x: Add support for AXP809 PMIC
The X-Powers AXP809 is a new PMIC that is paired with Allwinner's A80 SoC, along with a slave AXP806 PMIC. This PMIC is quite similar to the earlier AXP223, though the interrupts and regulator have changed a bit. This patch adds support for the interrupts and power button of the PMIC.
