[PATCH v2] hwmon: adt7475: constify attribute_group structures

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.

subject was not correct. Removed 'wusbhc' and '.'.
