We are standardizing pinctrl-single to use pin group node naming with -pins
suffix, so in this case main-cpsw2g-default-pins. The same applies for all
pin group node names. And please use -pins also for a single pin groups as
new pins may need to be added later on in some cases.

These changes are to make dtbs checks work for pinctrl-single yaml binding
as we mostly use a generic compatible and don't want to add all kind of
custom node name matches.

Regards,

Tony
