1483f91b30 cryptodev: remove v20 ABI compatibility
This reverts commit a0f0de06d457753c94688d551a6e8659b4d4e041 as the
rte_cryptodev_info_get function versioning was a temporary solution
to maintain ABI compatibility for ChaCha20-Poly1305 and is not
needed in 20.11.

Fixes: a0f0de06d457 ("cryptodev: fix ABI compatibility for ChaCha20-Poly1305")

85b00824ae crypto/scheduler: rename slave to worker
This patch replaces the usage of the word 'slave' with more
appropriate word 'worker' in QAT PMD and Scheduler PMD
as well as in their docs. Also the test app was modified
to use the new wording.

The Scheduler PMD's public API was modified according to the
previous deprecation notice:
rte_cryptodev_scheduler_slave_attach is now called
rte_cryptodev_scheduler_worker_attach,
rte_cryptodev_scheduler_slave_detach is
rte_cryptodev_scheduler_worker_detach,
rte_cryptodev_scheduler_slaves_get is
rte_cryptodev_scheduler_workers_get.

Also, the configuration value RTE_CRYPTODEV_SCHEDULER_MAX_NB_SLAVES
was renamed to RTE_CRYPTODEV_SCHEDULER_MAX_NB_WORKERS.

31f83163cf eal: add new prefetch write variants
This commit adds new rte_prefetchX_write() variants, that suggest to the
compiler to use a prefetch instruction with intention to write. As a
compiler builtin, the compiler can choose based on compilation target
what the best implementation for this instruction is.

Three versions are provided, targeting the different levels of cache.
