[PATCH v5 3/9] ARM: dts: wpcm450: Add global control registers (GCR) node

[Jonathan Neuschäfer]

The Global Control Registers (GCR) are a block of registers in Nuvoton
SoCs that expose misc functionality such as chip model and version
information or pinmux settings.

This patch adds a GCR node to nuvoton-wpcm450.dtsi in preparation for
enabling pinctrl on this SoC.
