net: dsa: remove cross-chip support from the MRP notifiers
With MRP hardware assist being supported only by the ocelot switch family, which by design does not support cross-chip bridging, the current match functions are at best a guess and have not been confirmed in any way to do anything relevant in a multi-switch topology. Drop the code and make the notifiers match only on the targeted switch port.
