drm/amd/powerplay: refine powerplay interface.
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.
