qed: Attention support patch series

Until now we've only enabled attention generation for the sake of
management firmware indications [required for link notifications].

This series enables [almost] all the attention sources of the HW,
currently for the sake of logging information relating to issues
experienced by HW. In future, infrastructure laid here would also be used
for the sake of the recovery process.

The first patch in the series is a semantic alignemnt of the code.
The later 3 patches incremently create said infrastructure and enrich
the logged information.
Notice #3 contains quite a bit of structures [consisting of ~1K lines]
that will eventually be removed and incorporated in the binary fw file.
