To support the detach feature, add a new mailbox channel to inform the remote processor on a detach. This signal allows the remote processor firmware to stop IPC communication and to reinitialize the resources for a re-attach. See 6257dfc1c412dcdbd76ca5fa92c8444222dbe5b0 for a patch that does the same for stm32mp15x-dkx boards.
