4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Giovanni Cabiddu <giovanni.cabiddu@...el.com>

commit 685ce0626840e2673fe64ea8807684f7324fec5f upstream.

Zero embedded ram in DH85x devices. This is not
needed for newer generations as it is done by HW.
