Earlier CONFIG_SERIAL_ARC_CONSOLE would unconditionally enable the legacy ARC UART based early console even if platform lacked that UART (e.g. nSIM OSCI platform). So a multi-platform image containing the 2 UART drivers won't work. Fix that by probing the driver only if "earlyprintk=ttyARC0" is present in cmdline.
