The avdd and the reference voltage are two different sources but the
reference voltage was assigned according to the avdd supply.
Add vref regulator structure and set the reference voltage according to
the vref supply from the devicetree.
In case vref supply is missing, reference voltage is set according to
the avdd supply for compatibility with old devicetrees.

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.
