The current OPP layer is based on a unique identifier (OPP_MPU, OPP_DSP, OPP_L3) which is not terribly portable or scalable for future devices.
Since we'd also like to be able to manage OPPs for any device (as recently agreed upon during an OMAP PM meeting in TI Bangalore[1]), this patch changes the OPP API to be device-based instead of unique-ID based. Essentially, this means passing a 'struct device' instead of a unique ID to determine which set of OPPs to be used. The main part of this patch is PATCH 08/12 where the OPP API changes are made. The earlier parts of the series are prep work for this and the remaining parts are updating users of the OPP API. Applies on top of current PM branch.
