dt-bindings: net: dsa: mediatek,mt7530: fix reset lines

- Add description for reset-gpios.
- Invalidate reset-gpios if mediatek,mcm is used. We cannot use multiple
reset lines at the same time.
- Invalidate mediatek,mcm if the compatible device is mediatek,mt7531.
There is no multi-chip module version of mediatek,mt7531.
- Require mediatek,mcm for mediatek,mt7621 as the compatible string is only
used for the multi-chip module version of MT7530.

GPIO to reset the switch. Use this if mediatek,mcm is not used.
This property is optional because some boards share the reset line with
other components which makes it impossible to probe the switch if the
reset line is used.
