Introduce port_setup_tc callback in mt7530 dsa driver in order to enable
dsa ports rate shaping via hw Token Bucket Filter (TBF) for hw switched
traffic. Enable hw TBF just for EN7581 SoC for the moment.

Is this because you didn't test it on the other models? Let me know if
that's the case and I'll test it.

yep, exactly. I have tested it just on EN7581 since I do not have any other
boards for testing at the moment. If you confirm it works on other SoCs too,
I can remove the limitation.

Seems to be working fine on MT7530. As we have tested this on the oldest
and newest models that use this switching IP, I'm going to assume it will
work on the other models as well. You can remove the limitation. Also,
please change MT7530_ERLCR_P and MT7530_GERLCR to MT753X_ERLCR_P and
MT753X_GERLCR.
