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.
