Putting NETDEV_LED_MODE_LINKUP in the same list of the netdev trigger
modes is wrong as it's used to set the link state of the device and not
to set a blink mode as it's done by NETDEV_LED_LINK, NETDEV_LED_TX and
NETDEV_LED_RX. It's also wrong to put this state in the same bitmap of the
netdev trigger mode and should be external to it.

Drop NETDEV_LED_MODE_LINKUP from mode list and convert to a simple bool
that will be true or false based on the carrier link. No functional
change intended.
