Add ADC1 and ADC2 support to STM32MP13 SoC family. The STM32MP131 provides only ADC2, while other STM32MP13 SoCs provide both ADC1 and ADC2. Internal channels support limitations: - VREFINT internal channel requires calibration data from OTP memory. The nvmem properties used to access OTP are not defined for time being, as OTP support is not yet enabled. - VBAT internal channel is not defined by default in SoC DT, and has be defined in board DT when needed, instead. This avoids unwanted current consumption on battery, when ADC conversions are performed on any other channels.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
