realtek: dsa: Add non-primary LAG ports to port matrix

Browse source 
If ports of a RTL93xx switch are not added to a port matrix then they are
not used for the link aggregation. As result, communication will then just
break on non-primary interfaces.

This can be reproduced in balanced-xor and 802.3ad bandwidth mode.
