[PATCH 0/2] Fix amdgpu detection of pci=realloc

[Mario Limonciello]

amdgpu needs to know the bus number the platform assigned a device to
be able to match firmware images against the right device.

This was previously adjusted to be a soft filter due to
commit 11c141672045f ("drm/amdgpu: Fix VFCT bus number matching with
soft filter") where if everything but the number matched to take a device.

This however fails when there are two identical devices.  Instead save the
initial bus number to the PCI device structure and then match that.
