As part of the simplification/cleanup of the iaa statistics, remove
the comp/decomp delay statistics.
They're actually not really useful and can be/are being more flexibly
generated using standard kernel tracing infrastructure.

The comp/decomp delay statistics currently have no callers; somehow
they were dropped during refactoring. There originally were also two
sets, one for the async algorithm, the other for the synchronous
version. Because the synchronous algorithm was dropped, one set should
be removed. To keep it consistent with the rest of the stats, and
since there's no ambiguity, remove the acomp/adecomp versions. Also
add back the callers.

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.
