drm/amd/pm: setup the framework to support Wifi RFI mitigation feature
With WBRF feature supported, as a driver responding to the frequencies,
amdgpu driver is able to do shadow pstate switching to mitigate possible
interference(between its (G-)DDR memory clocks and local radio module
frequency bands used by Wifi 6/6e/7).
--
v1->v2:
- update the prompt for feature support(Lijo)
v8->v9:
- update parameter document for smu_wbrf_event_handler(Simon)
v9->v10:
v10->v11:
- correct the logics for wbrf range sorting(Lijo)
v13:
- Fix the format issue (IIpo Jarvinen)
