Input: rework psmouse attributes to reduce module size
Rearrange attribute code to use generic show and set handlers instead of replicating them for every attribute; switch to using attribute_group instead of creating all attributes manually. All this saves about 4K. Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
