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.

The DPAA2 driver is not using the DPAA2 frame descriptor
software annotation area. This patch reduces the
PTA length to zero and adjust the RX Buffer Layout
accordingly.

This code in device init is not required, as the buffer
layout setting is also being programmed during queue configuration.

As the hardware determines which core will process which packet,
performance is boosted by direct cache warming/stashing as well
as by providing biasing for core-to-flow affinity, which ensures
that flow-specific data structures can remain in the core’s cache.
This patch enables the one cache line data stashing for packet
annotation data and packet context
