[PATCH] clk: register fixed-clock only if #clock-cells property is present

[Sylwester Nawrocki]

Mike, please ignore this patch for now. It turns out a less intrusive
change [1] is enough to fix the regressions on both imx and exynos.

I'm going to address the issue properly for next kernel release and
make exynos use regular fixed-clock driver, rather than registering
the external clock generators within the SoC main clock controller
driver.
