ARM: dts: exynos: Enable HDMI for Arndale Octa board
* GPIO for HDMI hot plug detect
GPX3_7 is used. The HPD awareness is done when the GPIO is active high.
* Enable HDMI block in Exynos5420
HDMI VDD and PLL consume 1.0V LDO6 (PVDD_ANAIP_1V0) and HDMI oscillator
requires 1.8V LDO7 (PVDD_ANAIP_1V8).
* Support HDMI display data channel
I2C #2 is assigned for the HDMI DDC. It enables the EDID access.
