PATCH 1/1 serial: samsung: only use earlycon for console

A configuration that enables earlycon but not the core console code causes a link error:

drivers/built-in.o: In function `setup_earlycon':
drivers/tty/serial/earlycon.c:70: undefined reference to `uart_parse_earlycon'

That error can be triggered by the newly added samsung earlycon support, which is missing a 'select' statement.

As suggested by Peter Hurley, solves the problem by moving the 'select SERIAL_EARLYCON' statement to the samsung console driver option, as it is done by all other console drivers.
