It is observed that the ramp rate measured on platform is not same as
advertised ramp rate due to platform design variation. On this case,
measured ramp rate is provided with property regulator-ramp-rate.

For such cases, add DT property for device specific configurations.

The Maxim MAX77686 PMIC is a multi-function device with regulators,
clocks and a RTC. The DT bindings for the clocks are in a separate
file but the bindings for the regulators are inside the mfd part.

To make it consistent with the clocks portion of the binding and
because is more natural to look for regulator bindings under the
bindings/regulator sub-directory, split the regulator portion of
the DT binding and add it as a separate file.
