This patch add support for configurable vdqcr exact flag.
This boost the performance, however this can give
side effects for some extra packet fetch. Which has been
taken care in the patch as well.

The actual descriptor for qm_mr_entry is 64-byte aligned.
But the original code plays a trick, and puts a u8 common
to the three descriptor subtypes in the union afterwards
outside their structure definitions.
Unfortunately since they compose a struct qm_fd with
alignment 8, this trick destroys the ability of the compiler
to understand what has happened, resulting in this kind of
problem:
drivers/bus/dpaa/include/fsl_qman.h:354:3: error:
alignment 1 of ‘struct <anonymous>’ is less than 8 [-Werror=packed-not-aligned]
} __packed dcern;
on gcc 8 / Fedora 28 out of the box.
This patch moves the u8 verb into the structure definitions
composed into the union, so the alignment of the parent struct
containing the alignment 8 object can also be seen to be
alignment 8 by the compiler. Uses of .verb are fixed up to use
.ern.verb (the same offset of +0 inside all the structs in
the union).
The final struct layout should be unchanged.

DPAA hardware support two kinds of queues:
1. Pull mode queue - where one needs to regularly pull the packets.
2. Push mode queue - where the hw pushes the packet to queue. These are
high performance queues, but limited in number.
This patch add the driver support for push mode queues.

The function rte_mem_virt2phy() is kept and used in functions which
works only with physical addresses.
For all other calls this function is replaced by rte_mem_virt2iova()
which does a direct mapping (no conversion) in the VA case.
Note: the new function rte_mem_virt2iova() function matches the
behaviour implemented in rte_mem_virt2phy() by the commit
680f6c12600f ("mem: honor IOVA mode in virt2phy")
