[PATCH v2] ARM: dts: Specify Odroid X2/U3 audio clock parents and rates

[Sylwester Nawrocki]

This ensures the core and the audio subsystem clocks are configured
properly, as expected by the sound machine driver. These bits are
missing to obtain proper audio sample rates in kernel v3.17, where
audio support for Odroid X2/U3 was first added.

It would be good to have it applied as a fix for v3.17.

First version of this patch was missing settings for EPLL, now it all
should be complete.
