net/bnxt: use common NQ ring

Thor queue scaling is currently limited by the number of NQs that
can be allocated. Fix by using a common NQ for all receive/transmit
rings instead of allocating a separate NQ for each ring.

net/bnxt: support CoS classification

Class of Service (CoS) is a way to manage multiple types of
traffic over a network to offer different types of services
to applications. CoS classification (priority to cosqueue) is
determined by the user and configured through the PF driver.
DPDK driver queries this configuration and maps the cos queue

net/dpaa2: support separate MC portal per process

Earlier, there was a single MCP handle which was available across
complete DPAA2 driver as well as part of the dev_private which was
shared by the secondary process.

For secondary, that is not valid and it would require to open its
own handle for the MC. This is eventually used as part of the DPNI
configuration.

By using the process_private member of the rte_eth_dev, it is
possible to keep separate handles per process. Without worry of
overwriting when secondary process accesses the dev_private.

net/bnxt: avoid null pointer dereference

Commit "bd0a14c99f65" enables the creation of a dedicated completion
ring for asynchronous event handling instead of handling these
events on a receive completion ring on non Stingray Platforms.

This causes a segfault due to NULL pointer dereference in
bnxt_alloc_async_cp_ring() on stingray. Fix this by checking the
pointer validity before accessing it.

Fixes: bd0a14c99f65 ("net/bnxt: use dedicated CPR for async events")

net/bnxt: reduce verbosity of logs

When IOMMU is available, EAL picks IOVA as VA as the default IOVA mode.
This causes the bnxt driver to log warning messages saying
"Memzone physical address same as virtual." and
"Using rte_mem_virt2iova()" during load.

Reduce the verbosity of logs to DEBUG. Reduced couple of other
logs level to DEBUG as well.

net/bnxt: support hot firmware upgrade for Stingray

FW sets HWRM_FUNC_QCAPS_OUTPUT_FLAGS_ERR_RECOVER_RELOAD
in HWRM_FUNC_QCAPS command, if device requires to invoke
fastboot FW during FW reset.

Driver has to poll for shutdown bit in fw_status register:
1. in case of hot fw upgrade, this bit will be set after all
   function drivers unregistered with fw.
2. in case of fw initiated error recovery, this bit will be
   set after fw has collected the core dump
