[ Upstream commit 70da9ee80228e6d98fd68e3c1db124c4461d283c ]

SoC clock drivers should suspend after every other drivers in the system,
which are using clocks and resume before them. The last stage for calling
suspend device callbacks is NOIRQ stage and there exists driver, which use
that state (dwmmc-exynos), so Exynos5433 clocks driver should also use it.
During the same stage, clocks driver will be always suspended after its
clients as a direct result of proper device probe order (deferred probe
reorders the suspend call sequence).
