Subject: [PATCH 12/14] firmware: dcdbas: constify attribute_group structures.

From: Arvind Yadav <arvind.yadav.cs@...il.com>

attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.
