Subject: [RFC PATCH 3/4] Export hid_register_report().

The Apple Magic Mouse (and probably other devices) publish reports that
are not called out in their HID report descriptors -- they only send them
when enabled through other writes to the device. This allows a driver to
handle these unlisted reports.
