[POWERPC] Fix PMI breakage in cbe_cbufreq driver The recent change to cell_defconfig to enable cpufreq on Cell exposed the fact that the cbe_cpufreq driver currently needs the PMI interface code to compile, but Kconfig doesn't make sure that the PMI interface code gets built if cbe_cpufreq is enabled. In fact cbe_cpufreq can work without PMI, so this ifdefs out the code that deals with PMI. This is a minimal solution for 2.6.22; a more comprehensive solution will be merged for 2.6.23.
