regulator: da9211: Constify struct regulator_desc

Browse Source 
'struct regulator_desc' is not modified in this driver.

Constifying this structure moves some data to a read-only section, so
increase overall security, especially when the structure holds some
function pointers.

On a x86_64, with allmodconfig:
Before:
======
   text	   data	    bss	    dec	    hex	filename
  13982	   2118	     16	  16116	   3ef4	drivers/regulator/da9211-regulator.o

After:
=====
   text	   data	    bss	    dec	    hex	filename
  14622	   1478	     16	  16116	   3ef4	drivers/regulator/da9211-regulator.o
