net: dsa: rzn1-a5psw: enable management frames for CPU port
[ Upstream commit
9e4b45f20c5aac786c728619e5ee746bffce1798 ]
Currently, management frame were discarded before reaching the CPU port due
to a misconfiguration of the MGMT_CONFIG register. Enable them by setting
the correct value in this register in order to correctly receive management
frame and handle STP.
