USB misc: make USB device id constant 

Author: Németh Márton <nm127@freemail.hu>

The id_table field of the struct usb_device_id is constant in 
so it is worth to make the initialization data also constant.

The semantic match that finds this kind of pattern is as follows:
(http://coccinelle.lip6.fr/)

// 
@r@
disable decl_init,const_decl_init;
identifier I1, I2, x;
@@
	struct I1 {
	  ...
	  const struct I2 *x;
	  ...

@s@

identifier r.x, E;

	struct I1 y = {
	  .x = E,
	};
@c@
