[PATCH] gpio: sim: constify struct configfs_attribute

[Bartosz Golaszewski]

In preparation for the constification of configfs attributes, make the
existing instances of struct configfs_attribute in gpio-sim const and
use the new st_attrs_const field of struct config_item_type.

Suggested-by: Thomas Weißschuh <thomas.weissschuh@xxxxxxxxxxxxx>
Closes: https://lore.kernel.org/all/20261016105712-707634de-c955-4c66-957a-2bdb84bca3e4@xxxxxxxxxxxxx/
