net: dsa: microchip: add switch offload forwarding support

Browse Source 
The flag offload_fwd_mark is set as the switch can forward frames by
itself.

This can be considered a fix to a problem introduced in commit
c2e866911e where the port membership are not set in sync.  The flag
offload_fwd_mark just needs to be set in tag_ksz.c to prevent the software
bridge from forwarding duplicate multicast frames.

Fixes: c2e866911e ("microchip: break KSZ9477 DSA driver into two files")
