This RFC is more of a proof of concept then a fully working solution as there
are a few unresolved issues we are hoping to get advise on from people on the
mailing list.
Until now extracting a card either by physical extraction (e.g. eGPU with
thunderbolt connection or by emulation through syfs
On device removal reroute all CPU mappings to dummy page per drm_file
instance or imported GEM object.

No point to try recovery if device is gone, just messes up things.

Track sysfs files in a list so they all can be removed during pci remove
since otherwise their removal after that causes crash because parent
folder was already removed during pci remove.

Some of the stuff in amdgpu_device_fini such as HW interrupts
disable and pending fences finilization must be done right away on
pci_remove while most of the stuff which relates to finilizing and releasing
driver data structures can be kept until drm_driver.release hook is called, i.e.
