[PATCH v3 4/5] cpufreq: apple-soc: Add new driver to control Apple SoC CPU P-states

[Hector Martin]

For the benefit of everyone else: I screwed up a reply from mobile and
ended up with a brief exchange offline, but here's the useful part of
the context. Viresh also pointed out dropping opp-shared if we don't use
that mechanism, so I'll do that for v4.

Here's the most complicated one we have so far: 20 cores and 6 clusters
sharing 2 OPP tables (mind the include and define fun - this is the best
way we could come up with to express two SoC dies glued together into
one MCM).
