[PATCH v2] USB: serial: ftdi_sio: Improve the accuracy of the baud rate generator by using round-to-closest instead of truncating when calculating baud rate divisors.

Improve baud-rate generation by using rounding-to-closest instead of truncation in divisor calculation. Results have been verified by logic analyzer on an FT232RT (232BM) chip. The following table shows the wanted baud rate, the baud rate obtained with the old method (truncation), with the new
