mfd: max14577: Add max14577 MFD driver core
This patch adds max14577 core/irq driver to support MUIC(Micro USB IC)
device and charger device and support irq domain method to control
internal interrupt of max14577 device. Also, this patch supports DT
binding with max14577_i2c_parse_dt().
The MAXIM 14577 chip contains Micro-USB Interface Circuit and Li+ Battery
Charger. It contains accessory and USB charger detection logic. It supports
USB 2.0 Hi-Speed, UART and stereo audio signals over Micro-USB connector.
The battery charger is compliant with the USB Battery Charging Specification
Revision 1.1. It has also SFOUT LDO output for powering USB devices.
