====================
net: ipa: update registers for other versions

This series updates IPA and GSI register definitions to permit more
versions of IPA hardware to be supported.  Most of the updates are
informational, updating comments to indicate which IPA versions
support each register and field.  But some registers are new and
others are deprecated.  In a few cases register fields are laid
out differently, and in these cases the changes are a little more
substantive.

I won't claim the result is 100% correct, but it's close, and should
allow all IPA versions 3.x through 4.x to be supported by the driver.
