net: dsa: mv88e6xxx: Preserve priority when setting CPU port. [ Upstream commit d8dc2c9676e614ef62f54a155b50076888c8a29a ] The 6390 family uses an extended register to set the port connected to the CPU. The lower 5 bits indicate the port, the upper three bits are the priority of the frames as they pass through the switch, what egress queue they should use, etc. Since frames being set to the CPU are typically management frames, BPDU, IGMP, ARP, etc set the priority to 7, the reset default, and the highest.
