ramips: DTS style improvements for mt7621_wevo_w2914ns-v2.dtsi

This does several trivial DTS style improvements:

- Move device name compatible to DTS files (and fix compatible in
  11acnas.dts)
- Remove xhci node as status is set to okay in mt7621.dtsi already
- 0x0 instead of 0x0000
- Simplify state_default node definition
