wifi: mt76: mt7925: add mt7925_mac_link_sta_assoc to associate per-link STA

The mt7925_mac_link_sta_add function currently associates the per-link STA.
We will extend this function when we implement the MLO functionality.

This patch only includes structural changes and does not involve any
logic changes.
