Octeontx2 PMD's mailbox client uses device memory to send messages
to mailbox server in the admin function Linux kernel driver.
The device memory used for the mailbox communication needs to
be qualified as volatile memory type to avoid unaligned device
memory accesses because of compiler's memory access coalescing.
This patch modifies the mailbox request and responses as volatile
type which were non-volatile earlier and accessed from unaligned
memory addresses which resulted in bus errors on Fedora 30 with
gcc 9.1.1.

This patch implements read clock api whose purpose is to return
raw clock ticks. Using this API real time ticks spent in
processing a packet can be known:
<read_clock val at any time> - mbuf->timestamp
Calling mbox for reading raw clock ticks in fastpath is very
expensive so its value is derived from time stamp counter(tsc)
using freq multiplier (ratio of raw clock ticks and tsc) and clock
delta (by how much tsc is lagging from raw clock value).

A huge drop in per core MPPS value was observed when PTP stack is
enabled. The reason behind the bottleneck is HW serialises the
transfer of all SQEs, which seeks timestamp capture, on the same
send DMA path. Hence only those packets which requires timestamp
capture should set SETTSTAMP in send mem alg.
With this patch timestamping would be done only for those packets
with PKT_TX_IEEE1588_TMST set.

When configure returns error, e.g. in case not supported offloads
(outer ip and sctp) driver released Rx,Tx queues. Then in case of
correct configuration the driver could not start due to queues already
released but the driver thought it was configured correctly.
Secondly if driver returns error from configuration librte_ethdev will
release, rx queues and tx queues, without chaining driver configured
state.
Fix that by 'releasing' configuration and changing driver state when
error is returned from otx2_nix_configure.

The incriminated commit broke the use of RTE_PCI_DRV_IOVA_AS_VA which
was intended to mean "driver only supports VA" but had been understood
as "driver supports both PA and VA" by most net drivers and used to let
dpdk processes to run as non root (which do not have access to physical
addresses on recent kernels).
The check on physical addresses actually closed the gap for those
drivers. We don't need to mark them with RTE_PCI_DRV_IOVA_AS_VA and this
flag can retain its intended meaning.
Document explicitly its meaning.
We can check that a driver requirement wrt to IOVA mode is fulfilled
before trying to probe a device.
Finally, document the heuristic used to select the IOVA mode and hope
that we won't break it again.
