crypto: iaa - Add compression mode management along with fixed mode

Browse source

Define an in-kernel API for adding and removing compression modes,
which can be used by kernel modules or other kernel code that
implements IAA compression modes.

Also add a separate file, iaa_crypto_comp_fixed.c, containing huffman
tables generated for the IAA 'fixed' compression mode.  Future
compression modes can be added in a similar fashion.

One or more crypto compression algorithms will be created for each
compression mode, each of which can be selected as the compression
algorithm to be used by a particular facility.
