regulator: max77675: Add MAX77675 regulator driver

Browse Source 
Add support for the Maxim Integrated MAX77675 PMIC regulator.

The MAX77675 is a compact, highly efficient SIMO (Single Inductor Multiple Output)
power management IC that provides four programmable buck-boost switching regulators
with only one inductor. It supports up to 700mA total output current and operates
from a single-cell Li-ion battery.

An integrated power-up sequencer and I2C interface allow flexible startup
configuration and runtime control.
