Re: [RFC PATCH net-next 4/4] net: dsa: b53: express b53_for_each_port in terms of dsa_switch_for_each_port

Merging the two allows us to remove the open-coded

Sadly I don't know if it's possible to completely get rid of
b53_for_each_port and replace it with dsa_switch_for_each_available_port,
especially for the platforms that use pdata and not OF bindings.

We should really be able to eliminate b53_for_each_port() entirely, let 
me try to submit a patch doing that when I come back from vacation or 
you can do it, and if there are bugs, I will address them.
