Document newly introduced modes and entry for the LED netdev trigger.

Add documentation for new modes:
- link_10
- link_100
- link_1000
- half_duplex
- full_duplex

Add documentation for new entry:
- hw_control

Also add additional info for the interval entry and the tx/rx modes with
the special case of hw_control ON.
