Subject: [PATCH net-next v2 8/8] net: ipa: kill ipa_version_supported()

The only place ipa_version_supported() is called is in the probe
function.  The version comes from the match data.  Rather than
checking the version validity separately, just consider anything
that has match data to be supported.
