dt-bindings: arm: Convert nuvoton,npcm750 binding to YAML

The general trend is to have devicetree bindings in YAML format, to allow automatic validation of bindings and devicetrees. Convert the NPCM SoC family's binding to YAML before it accumulates more entries. The nuvoton,npcm750-evb compatible string is introduced to keep the structure of the binding a little simpler.
