fwnode_graph_get_next_subnode() may return fwnode backed by ACPI device

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.

I think this is fine because of the bit in the ACPI spec that says all
bits are set if _STA is missing.   It seems much less likely we'll see
problems with hardware disappearing because _STA is there but says
the device isn't present.

Always a regression risk though :(
