drm/amd: Use amdgpu_device_pcie_dynamic_switching_supported() for SMU7

SMU7 does a check if the dGPU is inserted into a Rocket Lake system,
to turn off DPM.  Extend this check to all systems that have problems
with dynamic switching by using the
amdgpu_device_pcie_dynamic_switching_supported() helper.
