So based on the ti-sysc related dts comments, this patch should
work except you should be able to just leave out the clocks here
with the dts changes.

So the omap_hwmod_class, omap_hwmod_ocp_if and entry on the
dra76x_hwmod_ocp_ifs list are still needed with ti-sysc for a
while. Eventually that data will just come from the dts interconnect
hierarchy. For struct omap_hwmod_class_sysconfig, ti-sysc will
allocate and it based on the dts data.
