Platform module update - 2: module control API support

Added changes in #platform module for platform #module-control handle API. This will enable the necessary #platform #modules to #perform #module-init and #module-start operation in sequence. The specific platform #module can optionally define the #init operations in the module-control handle and register the control handle on module #registration. The platform will execute the init operation before executing the #start operation, through the control handle. This generalizes and reduces the future platform API changes by defining a #unified #API for all module control operations from the platform.
