net: dsa: Add helper to resolve bridge port from DSA port
In order for a driver to be able to query a bridge for information
about itself, e.g. reading out port flags, it has to use a netdev that
is known to the bridge. In the simple case, that is just the netdev
representing the port, e.g. swp0 or swp1 in this example:
br0
/ \
swp0 swp1
But in the case of an offloaded lag, this will be the bond or team
interface, e.g. bond0 in this example:
br0
/
bond0
/ \
swp0 swp1
Add a helper that hides some of this complexity from the
drivers. Then, redefine dsa_port_offloads_bridge_port using the helper
to avoid double accounting of the set of possible offloaded uppers.
