Subject: [PATCH 1/3] mfd: gateworks-gsc: Constify static struct attribute_group

The only usage of attr_group is to pass its address to
sysfs_create_group() and sysfs_remove_group(), both which takes pointers
to const attribute_group structs. Make it const to allow the compiler to
put it in read-only memory.

Done with the help of coccinelle.
