    mvebu: add reset delays of PHYs for Fortinet FortiGate 50E
    
    Add reset-(de)assert-us to ethernet PHYs on Fortinet FortiGate 50E to
    solve instability after HW resetting of PHYs. (ex.: restarting "network"
    service, etc...)
    
    Fixes: #13391
    Fixes: 102dc5a62506 ("mvebu: add support for Fortinet FortiGate 50E")
