> 
> Starting with i.MX8M* devices there are multiple spba-busses so we
> can't just search the whole DT for the first spba-bus match and take it.
> Instead we need to check for each device to which bus it belongs and
> setup the spba_{start,end}_addr accordingly per sdma_channel.
> 
> While on it, don't ignore errors from of_address_to_resource() if they
> are valid.
