igc: Add support for LEDs on i225/i226
Add support for LEDs on i225/i226. The LEDs can be controlled via sysfs
from user space using the netdev trigger. The LEDs are named as
igc-<bus><device>-<led> to be easily identified.
Offloading link speed and activity are supported. Other modes are simulated
in software by using on/off. Tested on Intel i225.
