[PATCH] drm/exynos: fix nested calls to lock mutex in drm resume

[Rahul Sharma]

From: Rahul Sharma <rahul.sha...@samsung.com>

While testing S2R on exynos board, system is hanging and
rebooting due to nested mutex_lock calls in exynos drm
resume callback. Changing the order of the calls is fixing
the issue.
