drm/exynos: exynos5433_decon: fix wrong state in decon_vblank_enable
BIT_IRQS_ENABLED was never set because of incorrect test in decon_vlank_enable() function, what resulted in lack of enabling vblank support. This patch fixes this issue. Signed-off-by: Marek Szyprowski <m.szyprowski@samsung.com> Signed-off-by: Inki Dae <inki.dae@samsung.com>
