Input: sidewinder - make array seq static const, makes object smaller

Don't populate the array seq on the stack but instead make it
static const. Makes the object code smaller by 30 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  22284	   3184	      0	  25468	   637c	drivers/input/joystick/sidewinder.o

After:
   text	   data	    bss	    dec	    hex	filename
  22158	   3280	      0	  25438	   635e	drivers/input/joystick/sidewinder.o
