[PATCH v2 2/2] ARM: dts: exynos: Add HDMI and Sil9234 to Trats2 board

[Maciej Purski]

Add HDMI and Sil9234 MHL converter to Trats2 board.
Following in SoC devices have been enabled:
- HDMI (HDMI signal encoder),
- Mixer (video buffer scanout device),
- I2C_5 bus (used for HDMI DDC)
- I2C_8 bus (used for HDMI_PHY control).

Based on previous work by:
