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
