Add a qdev gpio input in lasips2_init() by taking the existing lasips2_port_set_irq()
function, updating it accordingly and then renaming to lasips2_set_irq(). Use these
new qdev gpio inputs to wire up the PS2 keyboard and mouse devices.
At the same time set update_irq() and update_arg to NULL in ps2_kbd_init() and
ps2_mouse_init() to ensure that any accidental attempt to use the legacy update_irq()
function will cause a NULL pointer dereference.
