dt-bindings: arm/npcm: Add binding for global control registers (GCR)

A nuvoton,*-gcr node is present in nuvoton-common-npcm7xx.dtsi and will
be added to nuvoton-wpcm450.dtsi. It is necessary for the NPCM7xx and
WPCM450 pinctrl drivers, and may later be used to retrieve SoC model and
version information.

This patch adds a binding to describe this node.
