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.
