[PATCH 5/9] tty: moxa: constify pci_device_id.

[Arvind Yadav]

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
  14201	    656	   1760	  16617	   40e9	drivers/tty/moxa.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
  14329	    528	   1760	  16617	   40e9	drivers/tty/moxa.o
