       amd_powerplay_create/amd_powerplay_destroy.
    2. create pp_instance/smumgr/hwmgr/eventmgr in
       early init, destroy them when lata_fini.
    3. in sw_init, create and init asic private smumgr
       data, and free them when sw_fini.
    4. in hw_init, create and init asic private hwmgr
       data, and free them when hw_fini.
