ARC: [plat-arcfpga]: Enabling DeviceTree for Angel4 board
...
* 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

ARC: [DeviceTree] Basic support
...
This is minimal infrastructure needed for devicetree work.
It uses an a sample "skeleton" devicetree - embedded in kernel image -
to print the board, manufacturer by parsing the top-level "compatible"
string.
As of now we don't need any additional "board" specific "machine_desc".
TODO: support interpreting the command line as boot-loader passed dtb
