[ Upstream commit d9f866b2bb ]
fwnode_graph_get_next_subnode() may return fwnode backed by ACPI
device nodes and there has been no check these devices are present
in the system, unlike there has been on fwnode OF backend.
In order to provide consistent behaviour towards callers,
add a check for device presence by introducing
a new function acpi_get_next_present_subnode(), used as the
get_next_child_node() fwnode operation that also checks device
node presence.
