esp32: Update ADC driver update to the new esp_adc API.
This commit updates the ADC to use the new driver `esp_adc/adc_oneshot.h`.

There are several errata notes about not being able to change the bit-width
of the ADCs certain chips.  The only chip that can switch resolution to a
lower one is the normal ESP32.  ESP32 C2 and S3 are stuck at 12 bits, while
S2 is at 13 bits.

On the S2, you can change the resolution, but it has no effect on the
resolution, rather, it prevents attenuation from working at all!

The resolution is set to the maximum possible for each SoC, with the ESP32
being the only one not throwing errors when trying to set the bit-width to
9, 10, 11 or 12 bits using `ADC.width(bits)`.

MicroPython Documentation

The MicroPython documentation can be found at: http://docs.micropython.org/en/latest/

The documentation you see there is generated from the files in the docs tree: https://github.com/micropython/micropython/tree/master/docs

Building the documentation locally

If you're making changes to the documentation, you may want to build the documentation locally so that you can preview your changes.

Install Sphinx, and optionally (for the RTD-styling), sphinx_rtd_theme, preferably in a virtualenv:

 pip install sphinx
 pip install sphinx_rtd_theme

In micropython/docs, build the docs:

make html

You'll find the index page at micropython/docs/build/html/index.html.

Having readthedocs.org build the documentation

If you would like to have docs for forks/branches hosted on GitHub, GitLab or BitBucket an alternative to building the docs locally is to sign up for a free https://readthedocs.org account. The rough steps to follow are:

  1. sign-up for an account, unless you already have one
  2. in your account settings: add GitHub as a connected service (assuming you have forked this repo on github)
  3. in your account projects: import your forked/cloned micropython repository into readthedocs
  4. in the project's versions: add the branches you are developing on or for which you'd like readthedocs to auto-generate docs whenever you push a change

PDF manual generation

This can be achieved with:

make latexpdf

but requires a rather complete install of LaTeX with various extensions. On Debian/Ubuntu, try (1GB+ download):

apt install texlive-latex-recommended texlive-latex-extra texlive-xetex texlive-fonts-extra cm-super xindy
