Subject: [PATCH 3/5] leds: trigger: netdev: rename add namespace to netdev trigger enum modes

Rename NETDEV trigger enum modes to a more symbolic name and add a
namespace to them.

Also add __TRIGGER_NETDEV_MAX to identify the max modes of the netdev
trigger.

This is a cleanup to drop the define and no behaviour change are
intended.
