[PATCH] dma/dpaa2: set the vfa bit for rbp with vf

[Alvaro Karsz]

Set the VFA (Virtual Function Active) bit in
struct qdma_sdd -> rbpcmd_simple in order to use the route-by-port
functionality with PCIe virtual functions.

At the moment, a user wanting to enable route-by-port will call
rte_dpaa2_qdma_vchan_rbp_enable with a rte_dpaa2_qdma_rbp struct.

The struct includes the PCIe Physical and Virtual functions among other
things, which are then copied to qdma_sdd -> rbpcmd_simple, but the vfa
bit is never touched (the bit does exists in rbpcmd_simple),
so route-by-port with virtual functions won't work..

In order to fix this, a vfa bit is added to struct rte_dpaa2_qdma_rbp,
then is copied to qdma_sdd -> rbpcmd_simple.
