====================
net: ipa: some more cleanup

Version 3 of this series uses dev_err_probe() in the second patch,
as suggested by Heiner Kallweit.

Version 2 was sent to ensure the series was based on current
net-next/master, and added copyright updates to files touched.

The original introduction is below.

This is another fairly innocuous set of cleanup patches.

The first was motivated by a bug found that would affect IPA v4.5.
It maintain a new GSI address pointer; one is the "raw" (original
mapped) address, and the other will have been adjusted if necessary
for use on newer platforms.

The second just quiets some unnecessary noise during early probe.

The third fixes some errors that show up when IPA_VALIDATION is
enabled.

The last two just create helper functions to improve readability.
