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 MAX77802 is a chip that contains regulators, 2 32kHz clocks,
a RTC and an I2C interface to program the individual components.

The are already DT bindings for the regulators and clocks and
these reference to a bindings/mfd/max77802.txt file, that didn't
exist, for the details about the PMIC.

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

Some ECs need a little time for waking up before they can accept
SPI data at a high speed. Add a "google,cros-ec-spi-pre-delay"
property to the DT binding to configure this.

If this property isn't set, then no delay will be added. However,
if set it will cause a delay equal to the value passed to it to
be inserted at the beginning of a transaction.

This defines a new compatible option for MFD devices "simple-mfd" that will
make the OF core spawn child devices for all subnodes of that MFD device.
It is optional but handy for things like syscon and possibly other
simpler MFD devices.

Since there was no file to put the documentation in, I took this opportunity
to make a small writeup on MFD devices and add the compatible definition
there.
