The jsm driver fails when you try to use the TIOCSSERIAL ioctl.  The reason
is that the driver never sets uart_port.uartclk, causing the data received
using TIOCGSERIAL to not match the internal state of the driver.  This
patch fixes this problem by settings the uartclk to the value used by the
serial_core (16 times the baud base).
