Subject: [PATCH 08/11] 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
