From: Jun Yang <jun.yang@nxp.com>


This patch adds support for Virtual Storage profile (VSP) feature.
With VSP support when memory pool is created, the hw buffer pool id
i.e. bpid is not allocated; thhe bpid is identified by dpaa flow
create API.
The memory pool of RX queue is attached to specific BMan pool
according to the VSP ID when RX queue is setup.
for fmlib based hash queue, vsp base ID is assigned to each queue.
