[Keccak] Keccak_f implementation

This commit implements the full round of Keccak computation. It supports
all configurations of Width from 25 to 1600 bits. The number of rounds
is decided based on the given input width. For example, 800 bit Width
runs 22 rounds.

This implementation has the keccak states registers inside the module.
So, it has the message feed interface to support SHA3/SHAKE. The input
interface width is also configurable. But `Width`/`DInWidth` shall be
integer. For instance, 50b `Width` case, the `DInWidth` can be 25b but
not 27b.

About the project

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.

About this repository

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.

Documentation

The project contains comprehensive documentation of all IPs and tools. You can access it online at docs.opentitan.org.
