Alex Deucher bcfdd5d510 drm/radeon: fix check for port PM availability ... The ATPX method does not always exist on the dGPU, it may be located at the iGPU. The parent device of the iGPU is the root port for which bridge_d3 is false. This accidentally enables the legacy PM method which conflicts with port PM and prevented the dGPU from powering on. Ported from amdgpu commit: drm/amdgpu: fix check for port PM availability from Peter Wu.
