Add a default "stdout-path" to the kernel DTS file, as is present in many of the board DTS files elsewhere in the kernel tree. With this line present, earlyconsole can be enabled by simply passing "earlycon" on the kernel command line. No specific device details are necessary, since the kernel will use the stdout-path as the default.
