Subject: [PATCH] isdn: mISDN: netjet: 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
  10941	   1776	     16	  12733	   31bd isdn/hardware/mISDN/netjet.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  11005	   1712	     16	  12733	   31bd isdn/hardware/mISDN/netjet.o
