[PATCH v2] drm/amdgpu: expose amdgpu_sensors on pre-powerplay chips

[Samuel Pitoiset]

Totally untested but as long as read_sensor() has been recently
implemented for dpm based boards, amdgpu_sensors can now be
exposed.

v2: - make sure read_sensor is not NULL on dpm chips
    - keep sanity check for powerplay chips
