Samsung DeviceTree updates and improvements for 4.5

Browse Source 
1. eMMC/SDIO minor fixes usage of bindings on Snow and Peach
    Chromebooks.
 2. Remove FIMD from Odroid XU3-family because on XU3 it cannot be used
    yet and on XU3-Lite and XU4 it is not supported.
 3. Remove deprecated since June 2013 samsung,exynos5-hdmi.
 4. Add support for Pseudo Random Generator on Exynos4 (Trats2 for now).
    This depends on new SSS clock.
 5. Add rotator nodes for Exynos4 and Exynos5.
 6. Switch DWC3_1 on Odroid XU3 and XU3-Lite to peripheral mode because
    now it cannot be used as OTG.
 7. Cleanup the G2D usage on Exynos4 and add it to a proper domain
    in case of Exynos4210.
 8. Put MDMA1 in proper domain on Exynos4210 as well.
 9. Minor cleanups.
