[PATCH v1] arm64: dts: meson: a1: place pwrc and secure-monitor under /firmware

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.
