[PATCH] dmaengine: iop-adma: make array 'handler' static const, makes object smaller

[Colin King]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array 'handler' on the stack but instead make it
static const. Makes the object code smaller by 80 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  38225	   9084	     64	  47373	   b90d	drivers/dma/iop-adma.o

After:
   text	   data	    bss	    dec	    hex	filename
  38081	   9148	     64	  47293	   b8bd	drivers/dma/iop-adma.o

(gcc version 9.2.1, amd64)
