ACPI: scan: Add acpi_dev_get_next_consumer_dev()
In commit b83e2b306736 ("ACPI: scan: Add function to fetch dependent of ACPI device") we added a means of fetching the first device to declare itself dependent on another ACPI device in the _DEP method. One assumption in that patch was that there would only be a single consuming device, but this has not held. Replace that function with a new function that fetches the next consumer of a supplier device. Where no "previous" consumer is passed in, it behaves identically to the original function.
