Subject: [PATCH] cpufreq: powerpc: add missing MODULE_DESCRIPTION() macros

With ARCH=powerpc, make allmodconfig && make W=1 C=1 reports:
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/cpufreq/ppc-cbe-cpufreq.o
WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/cpufreq/powernv-cpufreq.o

Add the missing invocation of the MODULE_DESCRIPTION() macro to all
files which have a MODULE_LICENSE().

This includes three additional files which, although they did not
produce a warning with the powerpc allmodconfig configuration, may
cause this warning with specific options enabled in the kernel
configuration.

Corrections to these descriptions are welcomed. I'm not an expert in
this code so in most cases I've taken these descriptions directly from
code comments, Kconfig descriptions, or git logs.  History has shown
that in some cases these are originally wrong due to cut-n-paste
errors, and in other cases the drivers have evolved such that the
original information is no longer accurate.
