mfd: Add Maxim 77686 driver
This patch is device driver for MAX77686 chip. MAX77686 is PMIC and includes regulator and rtc on it. This driver is core of MAX77686 chip, so provides common support for accessing on-chip devices. It uses irq_domain to manage irq and regmap to read/write data to its register with i2c bus.
