Purpose:
Add the IPCC channel 4 as "detach" mailbox to support the remoteproc the feature added in [1].
The enable of this feature is a design choice. As consequence, the new mbox is declared
only for stm32mp157c-ed1 & stm32mp15x-dkx boards maintained by ST Microelectronics.
Aim:
Allow to send to the remote processor a HW signal on IPCC channel 4 when user space requests
to detach the main processor from the remote processor (e.g. a reboot of the Linux processor
on a crash).

Series Applied on stm32-next;
thanks
