clearfog: setup LEDs for SFP and LINE/EXPRESS indication
At first, refactor this so that we only have one single package for
userspace LED control. We're still using two system units because the
"status everything is OK" should only be given at the very end of the
boot. The regular LED setup for, e.g., link state monitoring on the
other hand should be performed ASAP.
There's no support for DTS-based trigger setup, which means that we have
to go via userspace. There's sadly no clear way of obtaining the GPIO#
from userspace (`lsgpio` and `gpiofind` return something else) so we
have to rely on debugfs :(.
