====================
net: ipa: tell GSI the IPA version

The GSI code that supports IPA avoids having knowledge about the
IPA layer it serves.  One result of this is that Boolean flags are
used during GSI initialization to convey that certain hardware
version-dependent special behaviors should be used.

A given version of IPA hardware uses a fixed/well-defined version
of GSI, so the IPA version really implies the GSI version.

If given only the IPA version, the GSI code supporting IPA can
use it to implement certain special behaviors required for IPA
*or* GSI.  This avoids the need to pass and maintain numerous
Boolean flags.
