Subject: [PATCH 05/28] video: fbdev: asiliantfb: 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
   4703	    512	      0	   5215	   145f	drivers/video/fbdev/asiliantfb.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   4767	    448	      0	   5215	   145f	drivers/video/fbdev/asiliantfb.o
