4.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Kai Chen <kai.chen@intel.com>
commit 4c4c565513cca1c53a12956640b5915727431631 upstream.
The decoupled MMIO feature doesn't work as intended by HW team. Enabling it with forcewake will only make debugging efforts more difficult, so let's disable it.
