video: fbdev: tridentfb: 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
  13206	   1232	     40	  14478	   388e	video/fbdev/tridentfb.o

File size after adding 'const':
   text	   data	    bss	    dec	    hex	filename
  13910	    528	     40	  14478	   388e	video/fbdev/tridentfb.o
