Bug description:
[impact]
While booting into OOBE, the screen freeze [AMD W7500 only]
[fix]
AMDGPU would allocate pcie gen/lane dynamically after ASPM is enabled.
Intel CPU may not support the dynamic lane/speed switching.
Solution is,
- Detect Intel x86 systems that don't support dynamic switching
- Override the input caps to maximum supported for that system
- Force all PCIe levels to use the same settings, rather than try to
configure each level differently.
[test cases]
1. boot with w7500
2. the screen doesn't freeze and can't find the error message in dmesg.
"amdgpu: [drm] *ERROR* [CRTC:72:crtc-0] flip_done timed out"
[where the issue could happen]
low, this could lead issue when setting higher speeds than supported.
