Subject: [PATCH 1/2] ARM: dts: stm32: Add coprocessor detach mbox on stm32mp157c-ed1 board
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.
