Use different coreboot revisions and patches per board

The release archives will be bigger, but this is a necessary change
that makes libreboot development easier.

At present, there are boards maintained in libreboot by different
people. By doing it this way, that becomes much easier. This is in
contrast to the present situation, where a change to one board
potentially affects all other boards, especially when updating to
a new version of coreboot.

Coreboot-libre scripts, download scripts, build scripts - everything.
The entire build system has been modified to reflect this change
of development.

For reasons of consistency, cbfstool and nvramtool are no longer
included in the util archives.
