I don't see a reason why we should exclude usb2 from base installation.
It is hardware support and all our devices do have usb ports so let's
support them in default in their completeness.

This is new format of repositories and it cleans little bit an idea
about what is authoritative hash we are going to use when we are tagging
new releases.

This is more appropriate naming for Turris 1.x routers because otherwise
just plain turris is confusing.

Lists were moved to same subdirectory as packages and packages and board
directories order is now flipped.

These are temporally lists to redirect previous versions of updater to
correct locations.

I am experiencing huge wifi instability on my all routers. It is clear
that CT drivers are no way more stable than they were when we tested
them two year or so ago. Let's use standard drivers instead.

The idea is that if you set some branch then it is most probably not
deploy signed branch and so we should include test key. On the other
hand if it is a deploy branch then this is not huge problem. The key
would be removed with first updater run.
