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).
