[PATCH 6.18.8] Revert "drm/amd: Check if ASPM is enabled from PCIe subsystem"

[Bert Karwatzki <spasswolf@web.de>]

This reverts commit 7294863a6f01248d72b61d38478978d638641bee.

This commit was erroneously applied again after commit 0ab5d711ec74 
("drm/amd: Refactor `amdgpu_aspm` to be evaluated per device")
removed it, leading to very hard to debug crashes, when used with a system with two
AMD GPUs of which only one supports ASPM.
