dpaa2-switch: add support for configuring learning state per port
Add support for configuring the learning state of a switch port.
When the user requests the HW learning to be disabled, a fast-age
procedure on that specific port is run so that previously learnt
addresses do not linger.
At device probe as well as on a bridge leave action, the ports are
configured with HW learning disabled since they are basically a
standalone port.
At the same time, at bridge join we inherit the bridge port BR_LEARNING
flag state and configure it on the switch port.
There were already some MC firmware ABI functions for changing the
learning state, but those were per FDB (bridging domain) and not per
port so we need to adjust those to use the new MC fw command which is
per port.
