David Lechner c553aa1b03 iio: adc: ad7173: fix compiling without gpiolib
Fix compiling the ad7173 driver when CONFIG_GPIOLIB is not set by
selecting GPIOLIB to be always enabled and remove the #if.

Commit 031bdc8aee ("iio: adc: ad7173: add calibration support") placed
unrelated code in the middle of the #if IS_ENABLED(CONFIG_GPIOLIB) block
which caused the reported compile error.

However, later commit 7530ed2aaa ("iio: adc: ad7173: add openwire
detection support for single conversions") makes use of the gpio regmap
even when we aren't providing gpio controller support. So it makes more
sense to always enable GPIOLIB rather than trying to make it optional.

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 reStructuredText 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.
