This patch adds software prefetching of the annotation which is
accessed by the driver to fetch the parsing results. The changes
also include as many instructions in between prefetching memory
and using it.

Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.
There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.
More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

With the current QBMAN multi-tx API, we need to create separate
enqueue descriptors for each of the packet which is required to
be enqueued to the hardware, once we support Atomic Queues
(with DCA) in dpaa2 drivers. Creating enqueue descriptor for
each packet is costly and have significant performance impact.
This patch introduces a flag parameter in the QBMAN multi-tx API,
so that DCA configuration (and later on ORP/ODP for ordered queues)
can be passed using flags and be updated in the EQCR using this flag.

As there were less number of CPU cycles in between when we access
the parse results and when we prefetch them, this patch modifies
the prefetch of the next parse result.

Parsing the annotation has multiple if checks in the data path.
These are reduced for common cases like IPv4/IPv6 and UDP/TCP
packets to enhance performance of these generic cases.

PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT are deprecated for a while.
As explained in [1], these flags were kept to let the applications and
PMDs move to the new flag. There is also a need to support Rx vlan
offload without vlan strip (at least for the ixgbe driver).
This patch renames the old flags for this feature, knowing that some
PMDs were using PKT_RX_VLAN_PKT and PKT_RX_QINQ_PKT to indicate that
the vlan tci has been saved in the mbuf structure.
It is likely that some PMDs do not set the proper flags when doing vlan
offload, and it would be worth making a pass on all of them.

The current code is sending 8 packet in each internal loop.
In some of the conditions, mbuf is being allocated or freed.
In case of error, the code is returning without taking care of
such buffer. It is better to send already prepared buffer and err
for the current failure only.

Typically when the PMD issues a Rx command to DPAA2 hardware,
the HW writes the available descriptors into the given memory.
The RX function then processes the frames and prepare them as
mbufs.
This patch adds support to issue another pull request to hardware
in another memory location, before we start processing the output
of the first request. This help in controlling the CPU cycles
wasted during the wait for the hardware to write the descriptors.
