84626a0d61 mempool: prevent objects from being across pages
When populating a mempool, ensure that objects are not located across
several pages, except if user did not request IOVA-contiguous objects.

23bdcedcd8 mempool: introduce helpers for populate and required size
Introduce new functions that can used by mempool drivers to
calculate required memory size and to populate mempool.

For now, these helpers just replace the *_default() functions
without change. They will be enhanced in next commit.

ce1f2c61ed mempool: remove callback to get capabilities
The callback was introduced to let generic code to know octeontx
mempool driver requirements to use single physically contiguous
memory chunk to store all objects and align object address to
total object size. Now these requirements are met using a new
callbacks to calculate required memory chunk size and to populate
objects using provided memory chunk.

These capability flags are not used anywhere else.

Restricting capabilities to flags is not generic and likely to
be insufficient to describe mempool driver features. If required
in the future, API which returns structured information may be
added.

efd785f994 mempool: rename addresses from physical to IOVA
The struct fields phys_addr_t rte_mempool_objhdr.physaddr and
rte_mempool_memhdr.phys_addr are renamed to rte_iova_t iova.
The deprecated names are kept in an anonymous union to avoid breaking
the API.

2baa3f0b7d mempool/octeontx: support memory area ops
Add support for register_memory_area ops in mempool driver.

Allow more than one HW pool when using OcteonTx mempool driver:
By storing each pool information to the list and find appropriate
list element by matching the rte_mempool pointers.
