[PATCH 1/2] dt-bindings: mfd: syscon: introduce no-auto-mmio property for syscons

[Dan Carpenter]

Generally, syscons are created automatically and accessed direclty via
MMIO however sometimes syscons might only be accessible from the secure
partition or through SCMI etc.  Introduce the no-auto-mmio property to
tell the operating system that the syscon needs to be handled manually.
