[PATCH] firewire: core-device: constify device_type structures

[Bhumika Goyal <bhumirks@gmail.com>]

Declare device_type structures as const as they are only stored in the type
field of a device structure. This field is of type const, so device_type
structures having similar properties can be declared const too.

File size before:
  text	   data	    bss	    dec	    hex	filename
   8120	    889	     72	   9081	   2379	drivers/firewire/core-device.o

File size after:
   text	   data	    bss	    dec	    hex	filename
   8248	    761	     72	   9081	   2379	drivers/firewire/core-device.o
