Convert arm,versatile-sysreg to DT schema

This short series converts the arm,versatile-sysreg binding to DT schema. The binding is already in use in examples which unsurprisingly needs a fix with the schema added.

This is part of getting rid of the remaining ~40 cases of compatibles without a schema in the examples.

The 'arm,versatile-sysreg' node in the example should not have '#address-cells' and '#size-cells' properties as the child node doesn't have 'reg'.

Convert the arm,versatile-sysreg binding to DT schema format.

The original binding was missing 'simple-mfd' and a 'panel' sub node which the only user (versatile-ab.dts) of this binding has.

Excellent, thanks!

I assume you will apply this to the binding tree or similar, else tell me what to do!

Yours,
