The SCP driver populates the platform device and checks the child nodes to identify whether it's a single-core SCP or a multi-core SCP. The resource structure of the multi-core SCP is a list of remoteproc instances which is different to the single-core SCP. The corresponding resource releasing action is based on the type of SCP.
