video: fbdev: nvidia: constify pci_device_id.

pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
   text	   data	    bss	    dec	    hex	filename
  12149	    768	     36	  12953	   3299	video/fbdev/nvidia/nvidia.o

File size after adding 'const':
   text	   data	    bss	    dec	    hex	filename
  12213	    704	     36	  12953	   3299	video/fbdev/nvidia/nvidia.o
