Previously, the DRM driver was the entry-point for the pci/platform bus probe() functions, and calls into NVKM to create an nvkm_device from pci/platform devices, then continues on with DRM init. Most of the code handling PCI/Tegra-specific functions has now been moved to NVKM (though prior to this commit, still *called* from DRM) and NVKM registers devices named "nvkm.device.<n>" on the auxiliary bus for each PCI or Tegra GPU in the system. The final step is to move pci/platform driver registration to NVKM, and have the DRM driver register as an auxiliary driver, from where it can gain access to the nvkm_device and proceed as it did before.
