regulator: axp20x: add support for the AXP717
The X-Powers AXP717 is a typical PMIC from X-Powers, featuring four DC/DC converters and 15 LDOs, on the regulator side. Describe the chip's voltage settings and switch registers, how the voltages are encoded, and connect this to the MFD device via its regulator ID.
