Randconfig testing found compile errors in drivers/of/unittest.c if
CONFIG_GPIOLIB is not set because CONFIG_OF_GPIO depends on
CONFIG_GPIOLIB. Make the gpio overlay test depend on CONFIG_OF_GPIO.
No code is modified, it is only moved to a different location and
protected with #ifdef CONFIG_OF_GPIO. An empty
of_unittest_overlay_gpio() is added in the #else.
Fixes: f4056e705b2e ("of: unittest: add overlay gpio test to catch gpio hog problem")

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.
