ARC: Fix earlycon build breakage

Commit ffb7fcd66f14 ("ARC: Dynamically determine BASE_BAUD from DeviceTree")
breaks arc:defconfig build:

       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

BASE_BAUD is only required for earlycon, which should depend on
CONFIG_SERIAL_EARLYCON.
