ARM: dts: Configure interconnect target module for omap3 sdma
We can now probe devices with device tree only configuration using
ti-sysc interconnect target module driver. Let's configure the
module, but keep the legacy "ti,hwmods" peroperty to avoid new boot
time warnings. The legacy property will be removed in later patches
together with the legacy platform data.
Note that we want to use separate compatible for omap34xx and
omap36xx so let's do that here too while at it.
