net: dsa: microchip: ksz8: Separate static MAC table operations for code reuse
[ Upstream commit f6636ff69ec4f2c94a5ee1d032b21cfe1e0a5678 ]
Move static MAC table operations to separate functions in order to reuse
the code for add/del_fdb. This is needed to address kernel warnings
caused by the lack of fdb add function support in the current driver.
