ARM: dts: stm32: Add coprocessor detach mbox on stm32mp15xx-osd32 SoM
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.
