Add the maxim MAX77686 power controller.

Create a new directory in drivers for power controllers.
Add the MAXIM MAX77686 power control support.

Accessing this controller requires I2C support.
Note that this will not build until the I2C usage is changed for
coreboot. I'm putting it in mainly because we need it soon
and I want to see if the new directory is acceptable.
