[CI] Optionally pass repository source to template

We have an Azure Pipelines template to install all build requirements for
OpenTitan, which assumes it is being called from the root of the
OpenTitan repository. This assumption is violated if the template is
included from another repository, as described in the docs at
https://docs.microsoft.com/en-us/azure/devops/pipelines/process/templates?view=azure-devops#use-other-repositories.

For this use case, this commit introduces a template parameter
`REPO_TOP`, which defaults to `.`. In cases where this default isn't
applicable (i.e. whenever this template is used from another repo), it
can be overwritten as needed.

The name `REPO_TOP` reflects the naming we use in the OpenTitan
documentation for the root of the opentitan repository.

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 either access it online or build it locally by following the steps below.

  1. Ensure that you have the required Python modules installed (to be executed in the repository root):
$ sudo apt install curl python3 python3-pip
$ pip3 install --user -r python-requirements.txt
  1. Execute the build script:
$ ./util/build_docs.py --preview

This compiles the documentation into ./build/docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:1313.
