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
   2643    1616      16    4275    10b3 video/fbdev/geode/gxfb_core.o

File size after adding 'const':
   text    data     bss     dec     hex filename
   2707    1552      16    4275    10b3 video/fbdev/geode/gxfb_core.o
