PATCH 1/1 drm/i915: Disable decoupled mmio for GEN9LP
From: Kai Chen <[email protected]>
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 just simply remove it.

Is the code going to be reused in the near future, i.e. why not remove the dead code as well?
