resource: Add the new device ops create/delete

To separate initialization and instance creation on resource driver,
the new ops create/delete are introduced. Now, each operation is
used as below:
 - init: Setup the common contexts for resource (called once)
 - exit: Clear the init-ed contexts (called once)
 - create: Create resource instance with an individual context
 - delete: Free own context and remove resource instance
