The DPAA2 DMA driver is an implementation of the dmadev APIs,
that provide means to initiate a DMA transaction from CPU.
Earlier this was part of RAW driver, but with DMA drivers
added as separate flavor of drivers, this driver is being
moved to DMA drivers.

The documentation on how to configure device instances using
accel-config can be improved by a number of changes:
* For initial example, when only configuring one queue, omit
configuration of a second engine, which is unused later.
* Add the "max-batch-size" setting to the options being configured for
each queue
* Add a final, more complete example, showing configuration of multiple
queues on a device.

For DMA device 0000:7d:0.0, the original generated dmadev name starts
with the "7d:0.0", which is not expected.
This patch uses rte_pci_device_name API to generates the dmadev name.

As per the deprecation notice, In the view of enabling unified driver
for octeontx2(cn9k)/octeontx3(cn10k), removing drivers/octeontx2
drivers and replace with drivers/cnxk/ which
supports both octeontx2(cn9k) and octeontx3(cn10k) SoCs.
This patch does the following
- Replace drivers/common/octeontx2/ with drivers/common/cnxk/
- Replace drivers/mempool/octeontx2/ with drivers/mempool/cnxk/
- Replace drivers/net/octeontx2/ with drivers/net/cnxk/
- Replace drivers/event/octeontx2/ with drivers/event/cnxk/
- Replace drivers/crypto/octeontx2/ with drivers/crypto/cnxk/
- Rename config/arm/arm64_octeontx2_linux_gcc as
config/arm/arm64_cn9k_linux_gcc
- Update the documentation and MAINTAINERS to reflect the same.
- Change the reference to OCTEONTX2 as OCTEON 9. Old release notes and
the kernel related documentation is not accounted for this change.

The DPAA DMA driver is an implementation of the dmadev APIs,
that provide means to initiate a DMA transaction from CPU.
The initiated DMA is performed without CPU being involved
in the actual DMA transaction. This is achieved via using
the QDMA controller of DPAA SoC.
