video: fbdev: pm2fb: 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
  11940	    660	     16	  12616	   3148	drivers/video/fbdev/pm2fb.o

File size after adding 'const':
   text	   data	    bss	    dec	    hex	filename
  12068	    532	     16	  12616	   3148	drivers/video/fbdev/pm2fb.o
