[PATCH v2] ARM: dts: duovero-parlor: Add HDMI output

[Florian Vaussard <florian.vaussard@epfl.ch>]

Add the necessary DTS nodes to enable the micro-HDMI output on Parlor
board.

Signed-off-by: Florian Vaussard <florian.vaussard@epfl.ch>

v1->v2:
- Rebased on Tony's omap-for-v3.16/dt-v2
- Use OMAP4_IOPAD macro
- Use hpd pin as GPIO with hdmi-connector
