[PATCH] ACPI: configfs: make config_item_type const

[Bhumika Goyal]

This is a followup patch for: https://lkml.org/lkml/2017/10/11/375 and
https://patchwork.kernel.org/patch/9999649/

Make these structures const as they are either passed to the functions
having the argument as const or stored as a reference in the "ci_type"
const field of a config_item structure.

Done using Coccienlle.
