[PATCH v2 5/5] rsa: update doxygen doc for RSA signature verification to mention PSS

[Quentin Schulz]

From: Quentin Schulz <quentin.schulz at cherry.de>

While the verification step originally only supported PKCS1.5 as padding
algorithm for the signature, it was later extended to add support for
PSS but the doxygen doc wasn't updated to reflect that so let's fix
that oversight.

Fixes: 061daa0b61f0 ("rsa: add support of padding pss")
