commit 18764b8 upstream.
This adds support for the LED's on most chip versions. Excluded are the old non-PCIe versions and RTL8125. RTL8125 has a different LED register layout, support for it will follow later.
LED's can be controlled from userspace using the netdev LED trigger.
Tested on RTL8168h.
Note: The driver can't know which LED's are actually physically wired. Therefore not every LED device may represent a physically available LED.
