This updates the cpufreq drivers in arch/powerpc so they build again
after the core cpufreq changes that broke them in commit
in835481d9bcd65720b473db6b38746a74a3964218.

When the PWRficient cpus are entered into powersavings states, the
astate is automatically dropped down to 0. While we still restore it
when we come out of idle, it can still cause some weird effects with
respect to performance (especially since it takes a while to ramp up to
higher astates).
So, to avoid this, don't enter power savings when the cpufreq driver
(or user) has set higher astates than 0.
The restore is still required, since there's a chance the astate has
been raised from the other cpu while the idling one was asleep.

There will be more product numbers in the future than just PA6T-1682M,
but they will share much of the features. Remove some of the explicit
references and compatibility checks with 1682M, and replace most of them
with the more generic term "PWRficient".
