The cros-ec-vbc driver is DT-only and there is a DT property that indicates if the EC has the VCB NVRAM, in such case instantiate the driver but don't instantiate on the other cases. To do this move the check code to its parent instead of play with the attribute group visibility. This changes a bit the actual behaviour. Before the patch if an EC doesn't have a VBC NVRAM an empty vbc folder is created in /sys/class/chromeos/<ec-device-name>, after the patch the empty folder is not created, so, the folder is only created if the vbc is set.

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.
