[PATCH v2 16/30] patman: Convert 'Series-xxx' tag errors into warnings

[Simon Glass]

If the Series-xxx tag is not recognised patman currently reports a fatal
error. This is inconvenient if a new feature is later added to patman that
an earlier version does not support.

Report a warning instead, to allow the user to take action if needed, but
still allow operation to proceed.
