Convert the device tree bindings for tm2-touchkey to the YAML format. While we're at it, clarify the descriptions a bit to make it clear that this driver can be used for many different MCUs that all implement a similar I2C protocol. Depending on the MCU the voltage requirements may be different, on some devices the controller uses 2.2V, 2.8V or even 3.3V for vcc-supply instead of 1.8V.

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.
