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. I could not find any documentation for the sysc register on this one, but it seems to work just fine with "ti,sysc-omap3-sham" compatible style configuration.
