I would not call it a rule just yet, but I guess there are further cases
were this could have been used. Perhaps you can all decide to use it for
the other Qualcomm dts as well.

For the X13s the, 'sc8280xp-x13s' is enough to uniquely define the
board and it mirrors 'sc8280xp-crd' (and using a shorter prefix makes
the commit logs easier to read).

The general suggestion is still to check 'git log --oneline' for the
files in question and use what appears to be the (recent) common prefix.
