video: fbdev: pm3fb: constify pci_device_id.

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
  10332     596      16   10944    2ac0 drivers/video/fbdev/pm3fb.o

File size after adding 'const':
   text    data     bss     dec     hex filename
  10396     532      16   10944    2ac0 drivers/video/fbdev/pm3fb.o
