Input: document that no new LED codes should be added
Add a comment to input-event-codes.h clarifying that no new LED
definitions should be added to the input subsystem. The existing
LED_* definitions are legacy and grandfathered for backwards
compatibility with userspace via evdev. Any new LED indicators
should instead use the dedicated LED subsystem.
