All extern functions of drivers/gpio/gpiolib.c are already
inside the Kernel documentation, as driver-api/gpio/index.rst
already includes it.
Placing a kernel-doc here will only cause mess, as the same symbol
will be placed on two parts of the document, causing breakages
in cross-references.
So, instead, add a cross-reference there.
This solves those Sphinx 3.1+ warnings:
