drm/nouveau: fix pcirom vbios shadow breakage from acpi rom patch
On nv50 it became impossible to attempt a PCI ROM shadow of the VBIOS, which will break some setups. This patch also removes the different ordering of shadow methods for pre-nv50 chipsets. The reason for the different ordering was paranoia, but it should hopefully be OK to try shadowing PRAMIN first. Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
