[PATCH v13 09/22] crypto: iaa - Deprecate exporting add/remove IAA compression modes.

[Kanchana P Sridhar <kanchana.p.sridhar@intel.com>]

There is no use case right now for kernel users to dynamically
add/remove IAA compression modes; hence this commit deletes the symbol
exports of add_iaa_compression_mode() and remove_iaa_compression_mode().

The only supported usage model of IAA compression modes is for the code
to be statically linked during the iaa_crypto module build,
e.g. iaa_crypto_comp_fixed.c, and for available modes to be registered
when the first IAA device wq is probed.
