ps2: implement ps2_reset() for the PS2_DEVICE QOM type based upon ps2_common_reset()

The functionality of ps2_common_reset() can be moved into a new ps2_reset() function
for the PS2_DEVICE QOM type. Update PS2DeviceClass to hold a reference to the parent
reset function and update the PS2_KBD_DEVICE and PS2_MOUSE_DEVICE types to use
device_class_set_parent_reset() accordingly.
