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
  19709    5024      32   24765    60bd video/fbdev/aty/radeon_base.o

File size after adding 'const':
   text    data     bss     dec     hex filename
  22893    1840      32   24765    60bd video/fbdev/aty/radeon_base.o
