of: Create of_console_check() for selecting a console specified in /chosen
The devicetree has a binding for specifying the console device in the
/chosen node, but the kernel doesn't use it consistently. This change
adds an API for testing if a device node is a console, and adds a
preferred console entry if it is.
At the same time this patch removes the of_device_is_stdout_path() API
since it is unused.
