* arc-uart platform device now populated dynamically, using
of_platform_populate() - applies to any other device whatsoever.
* uart in turn requires incore arc-intc to be also present in DT
* A irq-domain needs to be instantiated for IRQ requests by DT probed
device (e.g. arc-uart)
TODO: switch over to linear irq domain once all devs have been
transitioned to DT
