media: staging: rkisp1: rsz: make const array static, makes object smaller

Browse Source 
Don't populate the const array dev_names on the stack but instead it
static. Makes the object code smaller by 15 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  17091	   2648	     64	  19803	   4d5b	media/rkisp1/rkisp1-resizer.o

After:
   text	   data	    bss	    dec	    hex	filename
  17012	   2712	     64	  19788	   4d4c	media/rkisp1/rkisp1-resizer.o
