HID: add usage_index in struct hid_usage.
Currently, there is no way to know the index of the current field
in the .input_mapping and .event callbacks when this field is inside
an array of HID fields.
This patch adds this index to the struct hid_usage so that this
information is available to input_mapping and event callbacks.
