[PATCH] drm/exynos: modify condition in mixer and hdmi resume

[Rahul Sharma]

From: Prathyush K <prathyush.k at samsung.com>

If mixer is runtime suspended (by DPMS OFF), mixer_suspend
does not call mixer_poweroff and just returns. Similarily the
mixer_resume should not resume the mixer if mixer is
runtime_suspended. It should be done through DPMS ON.

The existing check is stopping the resume. This issue is fixed
by reversing the condiftion. It also holds good for hdmi driver.
