If a PHY doesn't use the integrated driver, SSDK use poll the phydev to
get the real PHY mode. qca807x use PSGMII as PHY mode and this specific
mode is not detected in qca SSDK while used in the entire driver.
Add support for it in the hsl_port_phydev_interface_mode_status_get
function used to translate PHY mode to the internal SSDK value.
