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)
