dpaa2-switch: add dpaa2_switch_port_to_bridge_port() helper
In preparation for adding offloading support for upper bond devices we
have to let the switchdev framework know if a specific bridge port is
offloaded or not, even if that brport is an upper device.
For this to happen, create the dpaa2_switch_port_to_bridge_port function
which will determine the bridge port corresponding to a particular DPAA2
switch interface and use it in the switchdev_bridge_port_offload call.
