Two cleanups
- These patches make Exynos DRM driver to use pm_runtime_resume_and_get()
function instead of m_runtime_get_sync() to deal with usage counter.
pm_runtime_get_sync() increases the usage counter even when it failed,
which could make callers to forget to decrease the usage counter.
pm_runtime_resume_and_get() decreases the usage counter regardless of
whether it failed or not.
