malta: correct UART baudrate

CONFIG_SYS_NS16550_CLK specifies the rate of the clock 16x the baud rate. The SMSC FDC37M81x datasheet states that a divider of 1 results in a UART at 115200 baud, thus the x16 clock rate is 115200 * 16. Previously the divider was left at 0 which led to a rate of 38400 baud regardless of CONFIG_BAUDRATE or the baudrate environment variable. Signed-off-by: Paul Burton <[email protected]>
