cpufreq/amd-pstate: Add offline, online and suspend callbacks for amd_pstate_driver

Rename and use the existing amd_pstate_epp callbacks for amd_pstate driver
as well. Remove the debug print in online callback while at it.

These callbacks will be needed to support the "Requested CPU Min Frequency"
BIOS option.
