Changed paths: A examples/zephyr/rpmsg_multi_services/boards/versal_rpu.conf

Log Message: ----------- examples: zephyr: add Versal RPU transport

Configure the RPMsg multi-services example to use the AMD IPI mailbox on Versal R5. Keep memory and linker placement outside the application so generated platform inputs remain the source of the RPU memory layout.

Log Message: ----------- examples: rpmsg: fix text response framing

The raw and TTY responders transmit one byte beyond their formatted prefix and payload. In the raw path this can expose stale buffer data, and adding the prefix to a maximum-sized received message can exceed the local response buffer.

Send exact prefix-plus-payload lengths and validate raw response construction. Increase the Linux utility's local receive buffer and bound text output by the length returned from read().

Log Message: ----------- examples: zephyr: configure safe RPU output

Linux can own the physical UART while loading an RPU application through remoteproc. Disable serial support for the AMD RPU targets and use the RAM console where required so the example does not contend for that UART.

Keep immediate logging for Versal Net, enable OpenAMP cache maintenance on Versal2, and retain the executable-memory settings used by the generated R52 memory policies.

Represent the supported platforms and tags as YAML sequences so Twister retains every entry and can build all AMD RPU targets.
