  This patch aims to add the basic NEON Rx path to iavf driver. Currently,
the main Rx function (_recv_raw_pkts_vec) and the functions it depends on
have been implemented. Also, NEON vector path has been added to
iavf_set_rx_function. The code compiles on N1SDP platform and some traffic
testing has been done with testpmd application. 

Still to be done as part of 22.07:
 - add FDIR extraction
 - functional testing
 - performance testing

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