Thomas Abraham 8b6076d47f ARM: dts: add board specific fixed rate clock nodes for Exynos based platforms
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.
