Subject: [PATCH 2/3] ACPI: property: Use ACPI functions in acpi_graph_get_next_endpoint() only

Calling fwnode_get_next_child_node() in ACPI implementation of the fwnode
property API is somewhat problematic as the latter is used in the
impelementation of the former. Instead of using
fwnode_get_next_child_node() in acpi_graph_get_next_endpoint(), call
acpi_get_next_subnode() directly instead.
