We do not need to have a reference to a dsa_switch, instead we should
pass a reference to a CPU dsa_port, change that. This is a preliminary
change to better support multiple CPU ports.

We have all the information we need in dsa_port, so use it instead of
repeating the same arguments over and over again.

There was no reason for duplicating the code that initializes
ds->enabled_port_mask in both dsa_parse_ports_dn() and
dsa_parse_ports(), instead move this to dsa_ds_parse() which is early
enough before ops->setup() has run.
While at it, we can now make dsa_is_cpu_port() check ds->cpu_port_mask
which is a step towards being multi-CPU port capable.
