net: cadence: macb: 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
    791     336       0    1127     467 net/ethernet/cadence/macb_pci.o

File size After adding 'const':
   text    data     bss     dec     hex filename
    855     272       0    1127     467 net/ethernet/cadence/macb_pci.o
