That reference gives a pretty good explanation. CONFIG_CRYPTO_FIPS
doesn't get you any closer to FIPS 140-2 validated kernel cryptography.

Unfortunately FIPS 140-2 validation conflicts rather violently with open
source software (and with software engineering best practice in general,
for that matter). Even if some benevolent benefactor ponied up the
quarter megabuck it would take to do an open source based kernel crypto
validation, it would be fossilized code obsolete before the validation
was even approved. Linux got to be as good as it is due to constant
refinement and improvement; FIPS validation presumes that it is possible
to write perfect code in one shot and that the environment that code
runs in never changes.
