crypto: msm: Add support for FIPS complience



FIPS140-2 certification asks to do a Power on Known Answer tests on each
algorithm which is getting certified. This patch implements the self tests
and hardcoded test vectors.  Also, we need to verify the integrity of
kernel as soon as it boots up. This patch also adds an ioctl for
integrity test along with ioctl to query FIPS status (pass / fail) from
user land.
also, The piece of code is added for FIPS compliance DRBG under
