ipq40xx: fix PHY subsystem compilation (phy_interface_num_ports())

Fixes:
drivers/net/phy/phy-core.c: In function 'phy_interface_num_ports':
drivers/net/phy/phy-core.c:107:9: error: enumeration value 'PHY_INTERFACE_MODE_PSGMII' not handled in switch [-Werror=switch]
  107 |         switch (interface) {
      |         ^~~~~~

Fixes: 8a7f667fb53e ("kernel: 5.15: backport v6.1 PHY changes required for Aquantia")
