====================
net: qrtr: Fixes and support receiving version 2 packets

On the latest Qualcomm platforms remote processors are sending packets with
version 2 of the message header. This series starts off with some fixes and
then refactors the qrtr code to support receiving messages of both version 1
and version 2.

As all remotes are backwards compatible transmitted packets continues to be
send as version 1, but some groundwork has been done to make this a per-link
property.
