Bluetooth: btintel: make array 'param' static, shrinks object size

Don't populate the const read-only array 'param' on the stack but instead
make it static. Makes the object code smaller by nearly 20 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  11605	   2629	     64	  14298	   37da	linux/drivers/bluetooth/btintel.o

After:
   text	   data	    bss	    dec	    hex	filename
  11531	   2685	     64	  14280	   37c8	linux/drivers/bluetooth/btintel.o

(gcc version 7.2.0 x86_64)
