QCA808x does not currently fill in the possible_interfaces. This leads to Phylink not being aware that it supports 2500Base-X as well so in cases where it is connected to a DSA switch like MV88E6393 it will limit that port to phy-mode set in the DTS. That means that if SGMII is used you are limited to 1G only while if 2500Base-X was set you are limited to 2.5G only. Populating the possible_interfaces fixes this.
