drm/amd/display: Add extra DMUB logging to track message timeout
[Description]
- Add logging for first DMUB inbox message that timed out to diagnostic
data
- It is useful to track the first failed message for debug purposes
because once DMUB becomes hung (typically on a message), it will
remain hung and all subsequent messages. In these cases we're
interested in knowing which is the first message that failed.
