Existing devices and drivers depended on device ID rather than type.
A new enumerator for all DPAA2 devices is introduced in this patch.
At this point, the probe would not be able to link DPAA2 devices
with the driver and I/O would not work. Subsequent patches will
fix this.

Stashing can also be configured by other drivers (for instance
event driver) passing cpu_id as an argument. This change
facilitates the same.

There are muliple help mc object, which are not an independent
device, but they are required for dpaa2 based devices.
This framework allows registration and handling of all such
mc devices.

DPAA2 hardware support the option to configure
multiple memories for Rx recv buffer (DPAA2-DQRR).
Each Rx request executing is called as 'DQ' request.
This patch adds routines to get information w.r.t each DQ request.

This patch adds generic functions for allowing dq storage
for the frame queues.
As the frame queues are common resource for different drivers
this is helpful.

The portal driver is bound to DPIO objects discovered on the fsl-mc bus and
provides services that:
- allow other drivers, such as the Ethernet driver, to enqueue and dequeue
frames for their respective objects
A system will typically allocate 1 DPIO object per CPU to allow queuing
operations to happen simultaneously across all CPUs.

Add support for using VFIO for dpaa2 based fsl-mc bus.
There are some differences in the way vfio used for fsl-mc bus
from the eal vfio.
- The scanning of bus for individual objects on the basis of
the DPRC container.
- The use and mapping of MC portal for object access
With the evolution of bus model, they can be further aligned with
eal vfio code.

This patch introduces the DPAA2 MC(Management complex Driver).
This is a minimal set of low level functions to send and
receive commands to the fsl-mc. It includes support for basic
management commands and commands to manipulate MC objects.
This is common to be used by various DPAA2 PMDs. e.g.net, crypto
and other drivers.
This is a low level library also used in kernel.

QBMAN, is a hardware block which interfaces with the other
accelerating hardware blocks (For e.g., WRIOP) on NXP's DPAA2
SoC for queue, buffer and packet scheduling.
This patch introduces a userspace driver for interfacing with
the QBMAN hw block.
The qbman-portal component provides APIs to do the low level
hardware bit twiddling for operations such as:
-initializing Qman software portals
-building and sending portal commands
-portal interrupt configuration and processing
This same/similar code is used in kernel and compat file is used
to make it working in user space.
