ARM: dts: Configure interconnect target module for omap4 hdmi

We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module and drop "ti,hwmods" peroperty as this module is a child node
of dispc and has no dependencies to to legacy platform data.

Note that we must disable smart idle modes for HDMI audio like we've
done with the legacy platform data. And HDMI needs both hdmi clock
and dss clock to operate.
