OpenBIOS: switch over to official OpenBIOS git repo

This update should preserve git history, and switches git.qemu-project.org
over to be a mirror of the new official git repo hosted at
https://github.com/openbios from a git-svn import of the old coreboot SVN
repository. All prior history from the SVN repository should still be preserved
(i.e. commit hashes are the same for historical commits).

No other source changes are made by this commit since both the old and new
HEADs contain the same source tree (albeit with difference metadata) whilst the
previous git-svn HEAD can be retrieved via the svn-head branch.
