HID: Add input_register callback.
Add input_register callback which gets called after
hid_configure_usage is called for all the reports
and before the input device is registered. This allows
individual drivers to do extra work like input mapping just
before device registration.
Based on discussions with David Herrmann <dh.herrmann@googlemail.com>
