Subject: [PATCH 05/11] rtlwifi: rtl8723be: 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
   3032	    912	      0	   3944	    f68	realtek/rtlwifi/rtl8723be/sw.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   3096	    848	      0	   3944	    f68	realtek/rtlwifi/rtl8723be/sw.o
