This commit adds driver support for ADC1 on all 8 supported series of stm32 with resolution and conversion time selection and calibration. Currently DMA is not supported for all series, and without it, zephyr won't be able to catch up ADC's end of conversion interrupt, so this version of the driver supports one channel conversion only. Users want multi-channel conversion should use multiple sequences in their app code. This driver uses LL lib rather than HAL because the current HAL lib for ADC will call HAL_DMA_* functions rather than using zephyr's common DMA interface, so that way the driver will break the consistency of the code. This driver has been tested on multiple nucleo boards including NUCLEO_F091RC/F103RB/F207ZG/F302R8/F401RE/F746ZG/L073RZ/L476RG and all passed the test cases in tests/drivers/adc/adc_api. If the external ADC line is floating, it may fail the tests since ADC may get 0V and the test cases think 0 is failing. Connect it to any voltage source between 0-3.3V will help passing the test cases. Signed-off-by: Song Qiang <songqiang1304521@gmail.com>

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.
The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.
The Zephyr kernel supports multiple architectures, including ARM Cortex-M,
Intel x86, ARC, Nios II, Tensilica Xtensa, and RISC-V, and a large number of
`supported boards`_.

Getting Started
***************
Welcome to Zephyr! See the `Introduction to Zephyr`_ for a high-level overview,
and the documentation's `Getting Started Guide`_ to start developing.
Community Support
*****************
.. TODO: add link to Asking for Help doc here when the latest page has it
Community support is provided via mailing lists and Slack; see the Resources
below for details.
Resources
*********
Here's a quick summary of resources to help you find your way around:
* **Documentation**: http://docs.zephyrproject.org (`Getting Started Guide`_)
* **Source Code**: https://github.com/zephyrproject-rtos/zephyr is the main
repository; https://elixir.bootlin.com/zephyr/latest/source contains a
searchable index
* **Releases**: https://zephyrproject.org/developers/#downloads.
* **Samples and example code**: see `Sample and Demo Code Examples`_
* **Mailing Lists**: users@lists.zephyrproject.org and
devel@lists.zephyrproject.org are the main user and developer mailing lists,
respectively. You can join the developer's list and search its archives at
`Zephyr Development mailing list`_. The other `Zephyr mailing list
subgroups`_ have their own archives and sign-up pages.
* **Chat**: Zephyr's Slack workspace is https://zephyrproject.slack.com. Use
this `Slack Invite`_ to register. There is also an IRC channel,
``#zephyrproject``, on `freenode`_.
* **Contributing**: see the `Contribution Guide`_
* **Wiki**: `Zephyr GitHub wiki`_
* **Issues**: https://github.com/zephyrproject-rtos/zephyr/issues
* **Security Issues**: Email vulnerabilities@zephyrproject.org to report
security issues; also see our `Security`_ documentation. Security issues are
tracked separately at https://zephyrprojectsec.atlassian.net.
