Don't populate the array reset_seq on the stack, instead make it
static.  Makes the object code smaller by over 50 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  11737	   6000	     64	  17801	   4589	drivers/media/i2c/ov2640.o

After:
   text	   data	    bss	    dec	    hex	filename
  11582	   6096	     64	  17742	   454e	drivers/media/i2c/ov2640.o
