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.

You don't need this structure... it's just one element inside, so you can
simply add it to `struct mtk_scp` instead: for readability purposes, you
can call this list `cluster_cores`.

After which
