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

File size After adding 'const':
   text    data     bss     dec     hex filename
   2839     848       0    3687     e67 realtek/rtlwifi/rtl8723ae/sw.o
