Krzysztof Kozlowski 53bf2776e3 ARM: dts: exynos: revert "add input clock to CMU in Exynos4412 Odroid" 
This reverts commit eaf2d2f689.

The commit eaf2d2f689 ("ARM: dts: exynos: add input clock to CMU in
Exynos4412 Odroid") breaks probing of usb3503 USB hub on Odroid U3.

It changes the order of clock drivers probe: the clkout (Exynos PMU)
driver is probed before the main clk-exynos4 driver.  The clkout driver
on Exynos4412 depends on clk-exynos4 but it does not support deferred
probe, therefore this dependency and changed probe order causes probe
failure.

The usb3503 USB hub on Odroid U3 on the other hand requires clkout
clock.  This can be seen in logs:

    [    5.007442] usb3503 0-0008: unable to request refclk (-517)
