[PATCH 1/4] led: unify led trigger tables

[Hubert Feurstein <h.feurstein@xxxxxxxxx>]

Currently we have two slightly different led-trigger tables. One in the
core module, and the other one in the led-triggers module. The one in the
core module, which is used to parse the device-tree triggers, is lacking
net-rx and net-tx.
