cpufreq/amd-pstate: Move registration after static function call update

Browse Source 
On shared memory designs the static functions need to work before
registration is done or the system can hang at bootup.

Move the registration later in amd_pstate_init() to solve this.

Fixes: b427ac4084 ("cpufreq/amd-pstate: Remove the redundant amd_pstate_set_driver() call")
