Add C906L remote processor for CV1800B SoC, which is an asymmetric processor typically running RTOS.
In the cover email, I saw that remoteproc also uses mailbox as the underlying communication. So I guess some mailbox-related properties will need to be added to the bindings? I suggest that these should be determined before officially merging this bindings.
Thanks， Chen
