[Buildroot] [PATCH 1/4] boot/opensbi: add support for version configuration

[Peter Korsgaard <peter@korsgaard.com>]

 > OpenSBI contains platform-specific code, so very much like Linux,

 > custom from Git. Support for other version control systems has not
 > been implemented for now, but could be added later if needed.

Maybe this should be inside the _LATEST_VERSION conditional in case the
license file ever changes, like we have done for the linux kernel?

But OK, that can be done later. Committed, thanks.
