Drivers supporting multiple clusters or multiple 'struct cpufreq_policy'
instances may need to keep per-policy data. If the core doesn't support them,
they might do it in the most unoptimized way: 'per-cpu' data.
This patch adds another field in 'struct cpufreq_policy': 'driver_data'. It
isn't accessed by core and is for driver's internal use.
