    mlx5: Decrease FW init timeout from 120 seconds to 5 seconds
    
    When encountering a failed NIC, the mlx5 driver will wait up to 120
    secs for the firmware to respond.  This timeout is absurdly huge, and
    leads to boot times of 40 minutes to over an hour on our servers when a
    NIC fails.  This is because the driver will attempt to attach to the
    failed NIC multiple times (once for each driver loaded after mlx5),
    and wait 2 minutes on each attempt.  This happens because the mlx5
    driver is still the best match for the device.  This delay then
    triggers watchdog timeouts in our environment, rendering servers
    with a failed NIC entirely unbootable without manual intervention.
    
    Note that FW_INIT_WARN_MESSAGE_INTERVAL must also be decreased, as
    it must be less than the init timeout.
