[PATCH v3 3/3] ARM: dts: exynos: Add support for HDMI audio on exynos5433-tm2

[Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx>]

This patch updates the sound node of the exynos5433-tm2 board
and adds clock tree configuration in order to support HDMI sound.

Signed-off-by: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx>
---
Changes since v2:
 - nodes sorted alphabetically, changed the assigned clock
   frequencies.

Changes since v1:
 - dropped unnecessary assigned-clock* properties for AUD PLL
   in cmu_top node,
 - changed default AUD PLL frequency so it is within recommended
   252...400 MHz range.
