[crypto] Update C code to use longer P-256 scalars. Update the cryptolib implementation and the SCA P-256 code to match new, longer P-256 scalar inputs. Also adjust all I/O buffers for scalars to have 512 bits so that reads don't produce runtime errors (since a 320-bit load on OTBN must be a 512-bit load).

OpenTitan is an open source silicon Root of Trust (RoT) project. OpenTitan will make the silicon RoT design and implementation more transparent, trustworthy, and secure for enterprises, platform providers, and chip manufacturers. OpenTitan is administered by lowRISC CIC as a collaborative project to produce high quality, open IP for instantiation as a full-featured product. See the OpenTitan site and OpenTitan docs for more information about the project.
This repository contains hardware, software and utilities written as part of the OpenTitan project. It is structured as monolithic repository, or “monorepo”, where all components live in one repository. It exists to enable collaboration across partners participating in the OpenTitan project.
The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
