Subject: drm/amd/display: update plane params before validation
Git-commit: 5449e07caa3a246c4ec79213978e70097e8b52aa
Patch-mainline: v4.16-rc5
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

This patch updates the dc's plane state with the parameters set by the
user side.
This is needed to validate the plane capabilities with the parameters
user space wants to set.
