Subject: [PATCH] tty: serial: fix earlycon dependency

parse_options() in drivers/tty/serial/earlycon.c calls
uart_parse_earlycon() in drivers/tty/serial/serial_core.c
therefore selecting SERIAL_EARLYCON should automatically
select SERIAL_CORE, otherwise will result in symbol not
found error during linking if SERIAL_CORE is not configured
as builtin
