Commit Message

This patch adds new cpu, codec subnodes according to the updated
"google,snow-audio-max98095" DT bindings and the I2S clock tree
configuration so sound on the HDMI interface can also be supported.

Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>

Changes since v2:
 - i2s0/#clock-cells property moved to exynos5250.dtsi
 - edited commit summary line.

Changes since v1:
 - changed order of codec in codec/cpu-dai property
   to match the DT bindings documentation.
