isdn: avm: c4: 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
  11803     544       1   12348    303c isdn/hardware/avm/c4.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  11931     416       1   12348    303c isdn/hardware/avm/c4.o
