ARM: dts: exynos: Fix HDMI-HPD line handling on Arndale

[ Upstream commit 21cb5a27483a3cfdbcb7508a06a30c0a485e1211 ]

HDMI-HPD was set active low, moreover by default pincontrol chip sets
pull-down on the pin. As a result HDMI driver assumes TV is always
connected regardless of actual state.  The patch fixes it.
