tty: serial: exar: 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
   4030	   1280	      0	   5310	   14be	tty/serial/8250/8250_exar.o

File size After adding 'const':
   text	   data	    bss	    dec	    hex	filename
   4958	    352	      0	   5310	   14be	tty/serial/8250/8250_exar.o
