The Realtek RT5640 codec is connected to the SoC's I2S interface. Describe this in the .dts together with the codec's LDO1 enable GPIO so audio can be played on the Endless Mini. While here, add a note about the realtek,ldo1-en-gpios for which the EC100 uses GPIO_BSD_EN. Due to driver limitations this pin cannot be used currently.

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.
