[PATCH AUTOSEL for 4.4 10/17] drm/exynos/decon5433: set STANDALONE_UPDATE_F on output enablement

[alexander . levin]

From: Andrzej Hajda <a.hajda@xxxxxxxxxxx>

[ Upstream commit 11d8bcef7a0399e1d2519f207fd575fc404306b4 ]

DECON_TV requires STANDALONE_UPDATE after output enabling, otherwise it does
not start. This change is neutral for DECON.
