For files like the drivers/serial/serial.c, it must include the platform file, as the CONFIG_SYS_NS16550_COM1 must reference to the definition in the platform definition files. Include the platform definition file in the config file, so that it would decouple the dependence for the driver files. Signed-off-by: Lei Wen <leiwen@marvell.com>
