This commit adds support to MAX77686 regulator driver,
based on a driver model regulator's API. It implements
almost all regulator operations, beside those for setting
and geting the Current value.
For proper bind and operation it requires the MAX77686 PMIC driver.
New file: drivers/power/regulator/max77686.c

This is the implementation of driver model PMIC driver.
The max77686 PMIC driver implements read/write operations and driver
bind method - to bind its childs.
This driver will try to bind the regulator devices by using it's child
info array with regulator prefixes and driver names. This should succeed
when compatible regulator driver is compiled. If no regulator driver found,
then the pmic can still provide read/write operations, and can be used with
PMIC function calls.

Allow to set the buck voltage for the max77686.
This will be used to reset the SMC LAN9730 ethernet on the odroids.

Some Exynos5250 silicon may require 1.05v on the MIF to be stable, so to be
safe we can default to 1.05v instead of 1.00v. This can be set optimally later
in the boot process by the kernel.
The 0x6 value for 1.05v comes from the MAX77686 datasheet.
