ARM: dts: Add Exynos5250 Snow Rev5+ support on exynos5250-snow-rev5
There are 2 revisions of the Exynos5250 Snow Chromebook that were shipped: Rev4 and Rev5. The only difference between these 2 revisions is the codec, Rev4 has a max98095 codec while Rev5 has a max98090. Mainline only supports Rev4 so this patch moves the common device nodes to a DTSI file and adds a DTS for the Exynos5250 Snow Rev5. The Snow Rev5 DTS is based on the DTS found in the ChromiumOS 3.8 tree.
