Subject: drm/exynos/decon5433: kill BIT_WIN_UPDATED flag
Git-commit: a48ff5010153946355d6d7e171807977e712c9c8
Patch-mainline: v4.13-rc1
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

The flag was used to trigger software update in TE IRQ handler only
if framebuffers were replaced. Since TE update is triggered always
when VBLANKs are enabled and after framebuffer replacement VBLANKs
are always enabled the flag becomes redundant.
