A minimal example of modifying cpufreq to use PowerOP on OMAP1710.

cpufreq utilizes 2 power parameters out of 8 available on omap1 platform.

The are two patches attached. The patch order is :

mpu.clock.reference.count.fix.patch
omap1.cpufreq.powerop.patch

mpu.clock.reference.count.fix.patch is just a trivial fix for a
minor issue.
