Ealier commit a325725633c26aa66ab940f762a6b0778edf76c0 did not attribute that virtio can be either PCI or a platform device and removed the .set_busid hook. Whereas only the "platform" instance should have been removed.
Since then, two things have happened:
- the driver manually calls drm_dev_set_unique, addressing the Xserver
regression - see commit 9785b4321b0bd701f8d21d3d3c676a7739a5cf22
- core itself calls drm_pci_set_busid, on drm_set_busid IOCTL setting
the busid, so we don't need to fallback to dev->unique - see commit 5c484cee7ef9c4fd29fa0ba09640d55960977145
With that in place we can remove the local workaround.

Gents, can someone double-check this please? Just in case.
