mfd: max77693: Use proper regmap for handling MUIC interrupts
Interrupts coming from Maxim77693 MUIC block (MicroUSB Interface Controller) were not handled at all because wrong regmap was used for MUIC's regmap_irq_chip. The MUIC component of Maxim 77693 uses different I2C address thus second regmap is created and used by max77693 extcon driver. The registers for MUIC interrupts are also in that block and should be handled by that second regmap. However the regmap irq chip for MUIC was configured with default regmap which could not read MUIC registers.
