[CELL] cbe_cpufreq: reorganize code
This patch reorganizes the code of the driver into three files. Two cbe_cpufreq_pmi.c and cbe_cpufreq_pervasive.c care about hardware. cbe_cpufreq.c contains the logic. There is no changed behaviour, except that the PMI related function is now located in a seperate module cbe_cpufreq_pmi. This module will be required by cbe_cpufreq, if CONFIG_CBE_CPUFREQ_PMI has been set. Signed-off-by: Christian Krafft <krafft@de.ibm.com> Signed-off-by: Arnd Bergmann <arnd.bergmann@de.ibm.com>
