lasips2: don't use vmstate_register() in lasips2_realize()

Since lasips2 is a qdev device then vmstate_ps2_mouse can be registered using
the DeviceClass vmsd field instead.

Note that due to the use of the base parameter in the original vmstate_register()
function call, this is actually a migration break for the HPPA B160L machine.
