Remove POWER7 and POWER7+ support
It's been a good long while since either OPAL POWER7 user touched a
machine, and even longer since they'd have been okay using an old
version rather than tracking master.
There's also been no testing of OPAL on POWER7 systems for an awfully
long time, so it's pretty safe to assume that it's very much bitrotted.
It also saves a whole 14kb of xz compressed payload space.
