  This patch adds the basic NEON Rx path to iavf driver, including
the main Rx function (_recv_raw_pkts_vec) and the functions it depends on.
Also, NEON vector path has been added to iavf_set_rx_function. Functional
testing with testpmd (rxonly and mac forwarding) and l3fwd have been done
on N1SDP platform. 

Performance testing will be done when Tx path is implemented. FDIR
extraction will be added at a later point as well.

Scatter and flex Rx paths will be deferred until a later release.

* Fixed compiler warning for PPC arch

* Updated commit message with testpmd rxonly mode test results

* Rebased patch onto main branch
