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
   5989     576       0    6565    19a5 isdn/hisax/hisax_fcpcipnp.o

File size After adding 'const':
   text    data     bss     dec     hex filename
   6085     480       0    6565    19a5 isdn/hisax/hisax_fcpcipnp.o
