[PATCH v3 06/11] ARM: dts: add xxti and xusbxti fixed rate clock nodes for exynos4 based platforms

[Thomas Abraham <thomas.abraham@xxxxxxxxxx>]

The clock frequency of xxti and xusbxti clocks is dependent on the frequency of the
on-board oscillator that is used to generate these clocks. So allow the frequency
of these clocks to be specfied from device tree.
