Subject: [PATCH 11/12] atm: eni: 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
  21565	    352	     56	  21973	   55d5	drivers/atm/eni.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  21661	    256	     56	  21973	   55d5	drivers/atm/eni.o
