provide the same functionality as rte_io_*mb APIs on all platforms, so
remove them and use rte_io_*mb instead.

When Rx/Tx queue was being created with DevX the allocated
doorbell record size was only uint64_t. That was definitely
less than size of CPU cacheline and it might have happened the
doorbell records attached to different queues handled by
different cores were allocated within same cacheline. It might
have caused the contention on doorbell record writing.
This patch extends the allocated memory size for doorbell
record to cacheline size.

The new kernel adds the names like "pf0" for Host PCI physical
function representor on Bluefield SmartNIC hosts. This patch
provides correct HPF representor recognition over the kernel
versions 5.7 and laters.
The following port naming formats are supported:
- missing physical port name (no sysfs/netlink key) at all,
master is assumed
- decimal digits (for example "12"), representor is
assumed, the value is the index of attached VF
- "p" followed by decimal digits, for example "p2", master
is assumed
- "pf" followed by PF index, for example "pf0", Host PF
representor is assumed on SmartNIC systems.
- "pf" followed by PF index concatenated with "vf" followed by
VF index, for example "pf0vf1", representor is assumed.
If index of VF is "-1" it is a special case of Host PF
representor, this representor must be indexed in devargs
as 65535, for example representor=[0-3,65535] will
allow representors for VF0, VF1, VF2, VF3 and for host PF.

Move mlx5 symbols in the map file to the INTERNAL section and add
__internal tags to their definitions.
Those symbols were exported in 20.02 and now (20.05) they are removed.
Avoid ABI comparison issues between 20.05/20.08 and 20.02 by adding the
suppress_file directive to libabigail.abignore file. This directive will
prevent loading mlx5 common symbols and no comparison will be performed.

The AltiVec header file breaks boolean type. [1] [2]
Currently the workaround was located only in mlx5 device.
Adding the trace module caused this issue to appear again, due to
order of includes, it keeps overriding the local fix.
This patch solves this issue by resetting the bool type, immediately
after it is being changed.

Use the MLX5_ASSERT macros instead of the standard assert clause.
Depends on the RTE_LIBRTE_MLX5_DEBUG configuration option to define it.
If RTE_LIBRTE_MLX5_DEBUG is enabled MLX5_ASSERT is equal to RTE_VERIFY
to bypass the global CONFIG_RTE_ENABLE_ASSERT option.
If RTE_LIBRTE_MLX5_DEBUG is disabled, the global CONFIG_RTE_ENABLE_ASSERT
can still make this assert active by calling RTE_VERIFY inside RTE_ASSERT.
