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.

The ePAPR standard says that: "the name of a node should be somewhat
generic, reflecting the function of the device and not its precise
programming model."
So, change the max77686 binding document example to use a generic
node name instead of using the chip's name.

The regulator-compatible property from the regulator DT binding was
deprecated. But the max77686 DT binding doc still suggest to use it
instead of the regulator node name's which is the correct approach.

If max77686 chip is instantiated from device tree, it is desirable to
have an OF clock provider to allow device tree based look-up of clocks.
This patch adds OF clock provider registration to the clk-max77686
driver.
