Future patches will convert this data to register hwmods by interfaces, rather than registering hwmods directly; and these pseudo-hwmods aren't associated with any interfaces. The hwmod code now resets processor IPs at the hwmod level, rather than individually. So, for example, if the IVA device driver code wishes to place one of the sequencer cores into reset, while leaving the other active, it must do so itself by calling the appropriate PRM functions. This patch will cause a change in the initialization behavior of the DSP, IVA, and IPU.
