Sherry Sun fcb10ee27f tty: serial: fsl_lpuart: fix the potential risk of division or modulo by zero
We should be very careful about the register values that will be used
for division or modulo operations, althrough the possibility that the
UARTBAUD register value is zero is very low, but we had better to deal
with the "bad data" of hardware in advance to avoid division or modulo
by zero leading to undefined kernel behavior.
