[PATCH v2 1/1] dt-bindings: net: convert nxp,lpc1850-dwmac.txt to yaml format

[Frank Li]

Convert nxp,lpc1850-dwmac.txt to yaml format.

Additional changes:
- compatible string add fallback as "nxp,lpc1850-dwmac", "snps,dwmac-3.611"
"snps,dwmac".
- add common interrupts, interrupt-names, clocks, clock-names, resets and
  reset-names properties.
- add ref snps,dwmac.yaml.
- add phy-mode in example to avoid dt_binding_check warning.
- update examples to align lpc18xx.dtsi.

changes in v2
- add Rob's review tags.
- change phy-mode to rgmii-id according to Andrew's suggestions.
