[PATCH v5 3/8] leds: trigger: netdev: drop NETDEV_LED_MODE_LINKUP from mode

[Ansuel Smith <ansuelsmth@xxxxxxxxx>]

NETDEV_LED_MODE_LINKUP is not strictly a blink mode but really a status
of the current situation of the carrier. It seems wrong to accomunate a
link status to the blink mode list and would cause some confusion as
someone would think that MODE_LINKUP is a separate mode that provide the
netdev trigger with the other 3 LINK, RX and TX.

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.
