Instead of renaming the default wireless led attached to the wireless chip, add a new led using the platform leds with the phy0tpt trigger set in userspace. When switching ar71xx to device tree, the same can be done by using the build in GPIO controller and without adding new bindings. Drop the now unused platform code.
