ARCH_NR_GPIOS is used locally in aggr_parse() as the maximum number
of GPIOs to be aggregated together by the driver since
commit ec75039d55 ("gpio: aggregator: Use bitmap_parselist() for
parsing GPIO offsets").
Don't rely on the total possible number of GPIOs in the system but
define a local arbitrary macro for that, set to 512 which should be
large enough as it is also the default value for ARCH_NR_GPIOS.

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.
