Before, meson power secure controller was a child of secure monitor node. But secure monitor isn't the bus in terms of device tree subsystem, so of_platform initialization code doesn't populate its children (of_platform_default_populate() API). Therefore in the current device tree meson power secure controller isn't probed at all. If we place meson power secure controller and secure monitor nodes under '/firmware', they will be populated automatically from of_platform initialization.
