Subject: [PATCH 20/28] video: fbdev: sunxvr500: 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
    170	    488	      0	    658	    292	drivers/video/fbdev/sunxvr500.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
    394	    264	      0	    658	    292	drivers/video/fbdev/sunxvr500.o
