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
  11749	    896	     24	  12669	   317d	video/fbdev/intelfb/intelfbdrv.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  12173	    472	     24	  12669	   317d	video/fbdev/intelfb/intelfbdrv.o
