fix(xilinx): runtime console to handle dt failure

Browse source 
If the Device Tree is missing or parsing fails in the runtime
console, the console still gets registered with zeroed DT values,
leading to a panic due to the absence of a console type.
Added fallback option and check for zero base address.
