Victor Zhao 6085f8289e drm/amdgpu: convert ptl_hw_supported to enum 
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.
