v2: add pp_check function to check pp_instance valid. 1. powerplay export two new interface to amdgpu, 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. 5. export powerplay state: PP_DPM_DISABLED. when user disabled powerplay or hwmgr/eventmgr init failed, powerplay return this state to amdgpu.
