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.
