Something to note about these "mandatory extensions" that are names for
things we already assumed were present - they're utterly useless and any
DT property should note their absence, not presence, in order to be of any
use. Anything parsing a DT cannot see "svbare" and gain any new
information, since the lack of it could be something that predates the
definition of "svbare" or something without "svbare".

Shit, but that's exactly why I deprecated riscv,isa.

Cheers,
Conor.
