cpufreq/amd-pstate: Pass the policy to amd_pstate_update() 



All callers of amd_pstate_update() already have a reference to the
cpufreq_policy object.

Pass the entire policy object and grab the cpudata using
"policy->driver_data" instead of passing the cpudata and unnecessarily
grabbing another read-side reference to the cpufreq policy object when
it is already available in the caller.

No functional changes intended.
