ps2: don't use vmstate_register() in ps2_kbd_init()
Since PS2_KBD_DEVICE is a qdev device then vmstate_ps2_keyboard can be registered
using the DeviceClass vmsd field instead. There is no need to use
qdev_set_legacy_instance_id() to ensure migration compatibility since the first 2
parameters to vmstate_register() are NULL and 0 respectively.
