[PATCH v1 2/3] hw/arm/aspeed_coprocessor: Clarify SCU/SCUIO/FMC fields are shared with PSP SoC to AST2700

Add a comment above Aspeed27x0CoprocessorState's scu_alias/scuio_alias/
fmc_alias and scu/scuio/fmc fields noting that they are not owned by
the coprocessor: they point at resources owned by the main PSP SoC,
only aliased into this coprocessor's own address space.

No functional change.
