lasips2: move mouse port initialisation to new lasips2_mouse_port_init() function

Browse source 
Move the initialisation of the mouse port from lasips2_init() to
a new lasips2_mouse_port_init() function which will be invoked using
object_initialize_child() during the LASIPS2 device init.

Update LASIPS2State so that it now holds the new LASIPS2MousePort child object and
ensure that it is realised in lasips2_realize().
