Subject: [PATCH 04/28] video: fbdev: sunxvr2500: 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
    390	    552	      0	    942	    3ae	drivers/video/fbdev/sunxvr2500.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
    686	    256	      0	    942	    3ae	drivers/video/fbdev/sunxvr2500.o
