Subject: [PATCH 16/28] video: fbdev: vermilion: 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
   7953	    568	     96	   8617	   21a9 fbdev/vermilion/vermilion.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   8017	    504	     96	   8617	   21a9 fbdev/vermilion/vermilion.o
