Documentation: gpio: Remove text about ARCH_NR_GPIOS
ARCH_NR_GPIOS have been removed, clean up the documentation. After this patch, the only place when ARCH_NR_GPIOS remains is in translations/zh_CN/gpio.txt and translations/zh_TW/gpio.txt. I don't have the skills to update that, anyway those two files are already out of sync as they are still mentionning ARCH_REQUIRE_GPIOLIB which was removed by commit 65053e1a7743 ("gpio: delete ARCH_[WANTS_OPTIONAL|REQUIRE]_GPIOLIB") Signed-off-by: Christophe Leroy <christophe.leroy@csgroup.eu> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

To force-enable this framework, a platform's Kconfig will "select" GPIOLIB,
else it is up to the user to configure support for GPIO.
-It may also provide a custom value for ARCH_NR_GPIOS, so that it better
-reflects the number of GPIOs in actual use on that platform, without
-wasting static table space. (It should count both built-in/SoC GPIOs and
-also ones on GPIO expanders.
-
If neither of these options are selected, the platform does not support
GPIOs through GPIO-lib and the code cannot be enabled by the user.
