(cherry picked from commit dce8195027f146467c9378efb2bb1b0859cb735e)
Cc: stable@vger.kernel.org

Convert ptl_hw_supported to enum with three states:
- AMDGPU_PTL_HW_UNINIT: not yet initialized
- AMDGPU_PTL_HW_SUPPORTED: initialized and supported
- AMDGPU_PTL_HW_NOT_SUPPORTED: initialized and not supported

This allows skipping PTL initialization attempts when hardware is
known to not support it, avoiding repeated initialization failures
after GPU resets.

v2:move ptl_hw_supported_state to AMDGPU_PTL_HW_NOT_SUPPORTED regardless
of error code during first time initialization. Print init fail log when
error code is not EOPNOTSUPP.

In SR-IOV mode, always query the latest PTL status from host via
psp_performance_monitor_hw() to ensure the sysfs shows real-time

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

The legacy xgmi ta without EXTEND_PEER_LINKS support in sriov still
reports it as enabled. It then fails when the command is called. Rely on
the host capability bit instead.

v2: Replace other instances of supports_ext_link_info with this method.
Including sysfs emission for xgmi_port_num. Now amd-smi xgmi --metric
will output N/A for all cells when port_nums cannot be mapped in sriov
