[PATCH net-next] Revert "net: dsa: constify cpu_dp member of dsa_port"

[Vivien Didelot]

We may have to pass a port's dedicated CPU port to port-wide functions
such as dsa_port_mdb_add, e.g. when offloading bridge device's MDB.

The DSA port-wide functions currently take a non-const struct dsa_port *
as first argument so we cannot make cpu_dp const yet, even though it'd
be more correct. Revert this patch and make cpu_dp non-const again.

This reverts commit 24a9332a58b7f41a0d36c35a2c6897242bffdbc0.
