DPAAX is a library used by various NXP drivers. In case of non-NXP
environment, this start spewing message about unavailability of
necessary environment.
This patch reduces the log level for certain messages as well as
reduces overall log-level. As a library, these message are not
necessarily relevant at higher log level, either.

In case the memory for nodes cannot be allocated, there is no need
to check for the length. Also, `node_count` is an unsigned value
and cannot be less than 0.

There is a possibility that either because of missing device tree entry
or lack of memory, the PA-VA table might not be available. But, the
table being transparent, the callers don't necessary check for its
initialization state. This is explicitly done during update and
translation call.

A common library, valid for dpaaX drivers, which is used to maintain
a local copy of PA->VA translations.
In case of physical addressing mode (one of the option for FSLMC, and
only option for DPAA bus), the addresses of descriptors Rx'd are
physical. These need to be converted into equivalent VA for rte_mbuf
and other similar calls.
Using the rte_mem_virt2iova or rte_mem_virt2phy is expensive. This
library is an attempt to reduce the overall cost associated with
this translation.
A small table is maintained, containing continuous entries
representing a continguous physical range. Each of these entries
stores the equivalent VA, which is fed during mempool creation, or
memory allocation/deallocation callbacks.
