ARM: OMAP4: hwmod data: add des 



This fixes the following error during kernel boot:

platform 480a5000.des: Cannot lookup hwmod 'des'

Unfortunately the DES module is only documented partly
in the OMAP4430 TRM. I found an old patch from Joel,
which I took over and updated for currently mainline.
