crypto: polyval - Add POLYVAL support
Add support for POLYVAL, an ε-Δ-universal hash function similar to
GHASH. This patch only uses POLYVAL as a component to implement HCTR2
mode. It should be noted that POLYVAL was originally specified for use
in AES-GCM-SIV (RFC 8452), but the kernel does not currently support
this mode.
POLYVAL is implemented as an shash algorithm. The implementation is
modified from ghash-generic.c.
For more information on POLYVAL see:
