The function mlxsw_sp_port_orig_get returns the vport from the physical
port if needed, based on the original device.
This patch addresses the case where the original device is a bridge.
If it is vlan unaware bridge, it returns the matching vport. If it is vlan
aware bridge, there is no matching vport, and it returns the original port.
