Subject: [PATCH 02/11] rtlwifi: rtl8192se: 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
   2817	   1040	      0	   3857	    f11 realtek/rtlwifi/rtl8192se/sw.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   3009	    848	      0	   3857	    f11 realtek/rtlwifi/rtl8192se/sw.o
