NXP Copyright has been wrongly worded with '(c)' at various places.
This patch removes these extra characters. It also removes
"All rights reserved".
Only NXP copyright syntax is changed. Freescale copyright is not

The bus name was stored with embedded double quotes.
Indeed the bus name is given with a string in a macro,
which is not used elsewhere.
These macros are useless because the buses are drivers,
so they must not have any API for the application writer.
The registration can be done with a hardcoded value without quotes.
There is another (small) benefit of not using macros for driver names:
it is to have a meaningful constructor function name.
For instance, it was businitfn_PCI_BUS_NAME instead of businitfn_pci.
The bus registration macro is also changed to use
the new RTE_INIT_PRIO macro, similar to RTE_INIT used for other drivers.
The priority is the highest (101) in order to be sure that the bus driver
is registered before its device drivers.

Dequeue from event device needs to process the event on
the basis of the hardware queue from which it is dequeued.
A callback is added into dpaa2_queue structure, to enable
event dequeue functionality to call that processing routine.

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.
