The difference of single-core SCP and multi-core SCP device tree is
the presence of child device nodes described SCP cores. 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.
