drm/amdgpu: add generic interfaces for PTL requests in virtualization
Add Performance Throttle Limiter (PTL) support for SR-IOV guest.
Since VF cannot communicate with PSP directly at runtime in SR-IOV
environment, use mailbox data fields to pass PTL parameters to PF,
and parse response status from host mailbox registers.
v2:
- remove redundent checks
- remove unused marco
