[PATCH 2/3] bsps/riscv: Handle ":" in chosen stdout-path

[Kevin Eyssartier]

The riscv_get_console_node function is searching the devices for the string specified in chosen in the fdt.
Unfortunately, this chosen string can contain parameters after the ":" character.

As specified in https://www.kernel.org/doc/Documentation/devicetree/bindings/chosen.txt :
    If the character ":" is present in the value, this terminates the path.

This was not handled in the function.
