Subject: cbe_cpufreq: fix build error

From: Christian Krafft <krafft@de.ibm.com>

The cbe_cpufreq driver should build without PMI
interface. The code that deals with PMI has been
#ifdef'ed out. This is not the optimal solution for now.
A later version of the cpufreq driver has been cleaned out
from all PMI code. Until that patch makes it into the kernel
use this patch to fix build issues when building cpufreq driver without PMI.
