[PATCH v4] ARM: dts: exynos: Enable HDMI for Arndale Octa board

[PATCH v4] ARM: dts: exynos: Enable HDMI for Arndale Octa board

[Milo Kim]

* 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.
