[PATCH 1/4] HID: add hid_type

[Jiri Slaby <jirislaby@gmail.com>]

Add type to the hid structure to distinguish to which device type
(now only mouse) we are talking to. Needed for per device type ignore
list support.

Note: this patch leaves the type as unknown for bluetooth devices,
there is not support for this in the hidp code.
