[U-Boot] U-Boot support for board(s) meesc, otc570

Note that the USART to use is defined differently than before:

/* serial console */
#define CONFIG_ATMEL_USART
#define CONFIG_USART_BASE		ATMEL_BASE_DBGU
#define	CONFIG_USART_ID			ATMEL_ID_SYS
#define CONFIG_BAUDRATE			115200
#define CONFIG_SYS_BAUDRATE_TABLE	{115200 , 19200, 38400, 57600, 9600 }

Best Regards,
Reinhard
