atm: idt77252: 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
  27702	    468	     16	  28186	   6e1a	drivers/atm/idt77252.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  27766	    404	     16	  28186	   6e1a	drivers/atm/idt77252.o
