Add support for optional debugfs statistics support for the IAA
Compression Accelerator. This is enabled by the kernel config item:
CRYPTO_DEV_IAA_CRYPTO_STATS
When enabled, the IAA crypto driver will generate statistics which can
be accessed at /sys/kernel/debug/iaa-crypto/.
See Documentation/driver-api/crypto/iax/iax-crypto.rst for details.

crypto: iaa - Add Intel IAA Compression Accelerator crypto driver core2023-12-15T09:52:53ZTom Zanussitom.zanussi@linux.intel.com2023-12-05T21:25:24Zurn:sha1:ea7a5cbb43696cfacf73e61916d1860ac30b5b2f
The Intel Analytics Accelerator (IAA) is a hardware accelerator that
provides very high thoughput compression/decompression compatible with
the DEFLATE compression standard described in RFC 1951, which is the
compression/decompression algorithm exported by this module.
Users can select IAA compress/decompress acceleration by specifying
one of the deflate-iaa* algorithms as the compression algorithm to use
by whatever facility allows asynchronous compression algorithms to be
selected.
For example, zswap can select the IAA fixed deflate algorithm
'deflate-iaa' via:
# echo deflate-iaa > /sys/module/zswap/parameters/compressor
This patch adds iaa_crypto as an idxd sub-driver and tracks iaa
devices and workqueues as they are probed or removed.
