Building arc:defconfig ... failed
--------------
Error log:

drivers/built-in.o: In function `of_setup_earlycon':
(.init.text+0xb3e): undefined reference to `arc_early_base_baud'
drivers/built-in.o: In function `setup_earlycon':
(.init.text+0xcd0): undefined reference to `arc_early_base_baud'
make: *** [vmlinux] Error 1

This is due to "ARC: Dynamically determine BASE_BAUD from DeviceTree".
arc:defconfig does not define CONFIG_SERIAL_8250 and thus also not
CONFIG_SERIAL_8250_CONSOLE, but it looks like it is mandatory
after this patch.
