ramips: fix GB-PC1 and GB-PC2 LEDs

Add the missing LEDs for GB-PC2. Some of these LEDs don't exist on the
device schematics. Tests on a GB-PC2 by me and Petr proved otherwise.

Remove ethblack-green and ethblue-green LEDs for GB-PC1. They are not wired
to GPIO 3 or 4 and the wiring is currently unknown.

Set ethyellow-orange to display link state and activity of the ethyellow
interface for GB-PC2.
