drm/amdgpu: Add kernel parameter support for ignoring bad page threshold
When a GPU hits the bad_page_threshold, it will not be initialized by
the amdgpu driver. This means that the table cannot be cleared, nor can
information gathering be performed (getting serial number, BDF, etc).
If the bad_page_threshold kernel parameter is set to -2,
continue to initialize the GPU, while printing a warning to dmesg that
this action has been done
v2: squash in Luben's fix to restore RAS info reporting
