From 75b6b7c255521b9ed29122bc2a34dfa21396bd79 Mon Sep 17 00:00:00 2001
From: Dmytro Laktyushkin <Dmytro.Laktyushkin@amd.com>

Subject: [PATCH 0455/4131] drm/amd/display: remove
GRPH_SURFACE_UPDATE_IMMEDIATE_EN field programming
This is causing asserts for dce 8 and 10 since they do not contain this
field. It is also unnecessary for later DCEs as it is left in it's
default state of 0
