It'd be good to get this merged and also build a new version of opensbi
which can be incorporated into QEMU. Without this change several new SBI
extensions won't be usable by Linux, even though the implementations are
present, because Linux checks that the SBI implementation version is at
least as big as the spec version where the extensions were frozen.

Thanks,
