Don't populate the array init_regs on the stack but instead make it
static. Makes the object code smaller by 57 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
  15935	   3600	    128	  19663	   4ccf	drivers/media/i2c/mt9m001.o

After:
   text	   data	    bss	    dec	    hex	filename
  15782	   3696	    128	  19606	   4c96	drivers/media/i2c/mt9m001.o

(gcc version 9.2.1, amd64)
