We don't need to "take" the information from anywhere; I've had most of
the comprehensive databases for a while now.
The problem with simply stuffing them into the kernel is that they're
big, and I tend to agree with folk that we don't really want large
single-use string tables in the kernel.
This is why the PCI code that identifies unattached drivers reads the
strings from a loadable file; once we can safely throw away loaded files,
we can load the file at boot/install/whenever time and then throw it away
once we're not interested anymore.
However, the real reason that most of these strings are being printed is
that the ISA probe order is bass-ackwards. The strings are printed
because we have good PnP information that tells us a device is present,
but we've already gone and believed the ISA hints and stuck a driver in
that's claiming some or all of these resources. The messages should be
silenced for 4.4, but the deeper problem needs to be addressed as well.
