Please instead introduce a set of defines without the SoC prefix
(i.e. CX, CX_AO, MX etc.). We've been putting this off for too long
and you're the first unlucky guy that submitted new RPMhPD support after
we've concluded it'd be the way to go! :D Sadly, we can't replace the
existing ones retroactively..
