dm: core: Allow iterating devices without uclass_get()
At present we have uclass_foreach_dev() which requires that uclass_get()
be called beforehand to find the uclass. This is good if we suspect that
that function might fail, but often we know that the uclass is available.
Add a new helper which does this uclass_get() automatically, so that only
the uclass ID is needed.
