commit 687ece117b624dbc6e981e9eee2a89f050e27d67

    microchipsw: lan969x: use network driver as a module
    
    Due to PTP conflicts with CONFIG_ALL_KMODS which causes the end images
    to end up with no switchdev driver included, lets switch to using the
    switchdev and PHY drivers as modules instead.
    
    Fixes: 88a404a2d177 ("microchipsw: add support for Microchip LAN969x switches")

    (cherry picked from commit b300a9e63dedb05df2535e65791fb3a898622b0c)
