Don't populate the array mclk_name on the stack but instead make it
static. Makes the object code smaller by 23 bytes:

Before:
   text	   data	    bss	    dec	    hex	filename
  38050	  11604	     64	  49718	   c236	linux/drivers/mfd/arizona-core.o

After:
   text	   data	    bss	    dec	    hex	filename
  38027	  11604	     64	  49695	   c21f	linux/drivers/mfd/arizona-core.o

(gcc version 8.2.0 x86_64)
