[top_earlgrey] Fix vendor in JTAG IDCODE
The JTAG IDCODE field uses a manufacturer ID from the JEDEC list of
manufacturers. This list organizes its entries in banks. Google is in
bank 9. The previously used number was from bank 10.
With this change, OpenOCD reports the right vendor:
```
$ /tools/openocd/bin/openocd -s util/openocd -f board/lowrisc-earlgrey-nexysvideo.cfg

Fixes #490
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.
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.
Download and install hugo-extended.
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
$ ./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.
