HID: google: extract Vivaldi hid feature mapping for use in hid-hammer
We need to support parsing the HID device in both the Vivaldi and the Hammer drivers so that we can properly expose the function row physmap to userspace when a hammer device uses a vivaldi keyboard layout for the function row keys. Extract the feature mapping logic from the vivaldi driver into an hid specific vivaldi library so we can use it from both HID drivers. To allow more code sharing we mandate that vivaldi data must be placed at the very beginning of the driver data attached to the HID device instance.
