mfd: max77686: Add Maxim 77802 PMIC support 

Maxim MAX77802 is a power management chip that contains 10 high
efficiency Buck regulators, 32 Low-dropout (LDO) regulators used
to power up application processors and peripherals, a 2-channel
32kHz clock outputs, a Real-Time-Clock (RTC) and a I2C interface
to program the individual regulators, clocks outputs and the RTC.

This patch adds support for MAX77802 to the MAX77686 driver and is
based on a driver added to the Chrome OS kernel 3.8 by Simon Glass.

Say yes here to add support for Maxim Semiconductor MAX77686.
This is a Power Management IC with RTC on chip.
Say yes here to add support for Maxim Semiconductor MAX77686 and
MAX77802 which are Power Management IC with an RTC on chip.
This driver provides common support for accessing the device;
additional drivers must be enabled in order to use the functionality
of the device.
