[PATCH] dt-bindings: net: dsa: Fix realtek-smi example

The 'ports' node is not supposed to have a 'reg' property at all, in
fact, doing so will lead to dtc issuing warnings looking like these:

arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts:109.4-14: Warning (reg_format): /switch/ports:reg: property has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)

arch/arm/boot/dts/bcm47094-asus-rt-ac88u.dts:106.9-149.5: Warning (avoid_default_addr_size): /switch/ports: Relying on default #size-cells value

Fix the example by remove the stray 'reg' property.

Then just fix this in the conversion.

Hi Rob,

I'm not sure if I got your suggestion. Should I post the new patch
in-reply to this thread?
It is related but something completely different.

I sent YAML conversion v1 a little while ago.
https://lore.kernel.org/netdev/20211228072645.32341-1-luizluca@gmail.com/

I'll send v2 soon. I'll mention it in this thread when I do it.

Best,

Luiz
