[PATCH v3] dt-bindings: arm: Convert nuvoton,npcm750 binding to YAML

[Jonathan Neuschäfer]

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.

v3:
- In this version, I removed the nuvoton,npcm750-evb compatible string
  again. I had previously introduced it to simplify the binding a little
  bit, but Tomer Maimon suggested to keep /compatible of
  nuvoton-npcm750-evb.dts as-is (i.e. only use "nuvoton,npcm750", no
  board-specific string).
  Because of this change, I am not including Rob Herring's R-b tag.

v2:
- https://lore.kernel.org/lkml/20210116010907.3475405-1-j.neuschaefer@gmx.net/
  https://lore.kernel.org/lkml/20210303154622.3018839-1-j.neuschaefer@gmx.net/
- Fix indentation to satisfy yamllint
- Fix $schema line
