Start using ti-sysc with device tree data for omap4 l4 devices

With ti-sysc driver working for most use cases, we can start converting
the omap variant SoCs to use device tree data for the interconnect target
modules instead of the legacy hwmod platform data.

We start with omap4 l4 devices excluding the ones that still depend on
a reset controller driver like DSP MMU. And we don't yet convert the l4
ABE instance as that needs a bit more work.

We also add a proper interconnect hierarchy for the devices while at it
to make further work on genpd easier and to avoid most deferred probe
issues.

At this point we are not dropping any platform data, and we initially
still use it to validate the dts data. Then in later merge cycles we
can start dropping the related platform data.
