[Intel-gfx] [PATCH 2/9] drm/i915: Fix async flip with decryption and/or DPT

From: Ville Syrjälä We're currently forgetting to set the PLANE_SURF_DECRYPT flag in the async flip path. So if the hardware were to latch that bit despite this being an async flip we'd start scanning out garbage. And if it doesn't latch it then I guess we'd just end up with a weird register
