Tushar Behera 80f78ad8af ARM: dts: Add sound node for exynos5250-snow board
The audio codec on Snow board, MAX98095 is connected on I2C7 bus.
Also it requires the GPX1-7 line to be pulled up.

Updated Snow DTS file to incorporate above changes and added a
sound node to instantiate the I2S-based sound card.
