[topgen] Add PINMUX & PADS to hjson

This is a Pull-Request for defining PINMUX and PADS in hjson and
generating complete hjson struct to helping pinmux/ pads generators.
Purpose of this PR is to gather wide agreement what will come to the top
and the suggested data structure in `top_earlgrey.hjson` for PINMUX and
PADS.

This PR also removes unused hjson (deprecated) and clean-up the merge
script to make common functions to be used in validate, merge, and
inside the template.

OpenTitan

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.

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 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 ./opentitan-docs and starts a local server, which allows you to access the documentation at http://127.0.0.1:5500.
