Series crypto: Add new compression modes for zlib and IAA | expand

Commit Message

Andre Glover March 28, 2024, 5:44 p.m. UTC 
Update optional debugfs statistics support for IAA with additional software
compression statistics. The software compression statistics will track
instances where iaa falls back to software deflate (e.g. when the source
data input length is greater than 4KB).
