[gpio dv] Scoreboard updates to compare against correct(latched) reg read data

1. gpio_env_pkg.sv: Updated structure gpio_reg_update_due definition
2. gpio_scoreboard.sv: rtl provides latched values as register read data
   updated prediction for data_in and intr_state registers to match this
   This update makes scoreboard much more reliable and roust for random
   stimulus.
   Also updated scoreboard for "interrupt test" register functionality.
3. gpio_intr_with_filter_rand_intr_event_vseq.sv: Delay intr_state read to
   account for rtl delay
4. gpio_rand_intr_trigger_vseq.sv: Updated to provide more meaningful random
   stimulus that can hit corner cases for intrrupt updates, clearing and
   read back

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.
