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:

File size after adding 'const':
   text    data     bss     dec     hex filename
  18686     672      48   19406    4bce video/fbdev/aty/atyfb_base.o
