[net-next PATCH v5 10/14] net: dsa: qca8k: move port FDB/MDB function to common code

From: Christian Marangi
Date: Wed Jul 27 2022 - 07:36:54 EST

The same port FDB/MDB function are used by drivers based on qca8k family
switch. Move them to common code to make them accessible also by other
drivers.
Also drop bulk read/write functions and make them static
