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. Signed-off-by: Tom Zanussi <tom.zanussi@linux.intel.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
