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
  19916	   1240	      8	  21164	   52ac fbdev/savage/savagefb_driver.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  20684	    472	      8	  21164	   52ac fbdev/savage/savagefb_driver.o
