mfd: axp20x: Add support for AXP717 PMIC
The AXP717a is a PMIC chip produced by X-Powers, it can be connected to an I2C or RSB bus. It's a rather complete PMIC, with many regulators, interrupts, an ADC and battery charging functionality. It also offer USB type-C CC pin handling. Describe the regmap and the MFD bits, along with the registers exposed via I2C or RSB. This covers the regulator, interrupts and power key devices for now. Advertise the device using the new compatible string.
