Rob Herring e62fc18213 dt-bindings: Add missing (unevaluated|additional)Properties on child node schemas
Just as unevaluatedProperties or additionalProperties are required at
the top level of schemas, they should (and will) also be required for
child node schemas. That ensures only documented properties are
present.

Add unevaluatedProperties or additionalProperties as appropriate, and
then add any missing properties flagged by the addition.

MT6357 is a power management system chip containing 5 buck
converters and 29 LDOs. Supported features are audio codec,
USB battery charging, fuel gauge, RTC
This is a multifunction device with the following sub modules:
- Regulator
- RTC
- Keys
It is interfaced to host controller using SPI interface by a proprietary hardware
called PMIC wrapper or pwrap. This MFD is a child device of pwrap.
See the following for pwrap node definitions:
