The main reason for the output of quirks is for those that you can't
find any other way.  Blocksize is something you can obtain from
diskinfo, so what is the point of putting it in quirks?  Just to spam
dmesg?

A fair point.  I would prefer to address this issue in a followup
commit, perhaps as part of harmonizing the quirk tables.  See below.

Yes, but this problem already exists and is not made worse by this
change.  We can debate this issue, but I consider it a separate one
from converting the quirk entry type.

In ata, there aren't any quirks aside from 4K.
