From Gavin Atkinson in FreeBSD SVN rev 238778:

The baud rate on CP1201/2/3 devices can be set in one of two ways:
 - The USLCOM_SET_BAUD_DIV command (0x01)
 - The USLCOM_SET_BAUD_RATE command (0x13)

Devices based on the CP1204 will only accept the latter command, and ignore
the former.  As the latter command works on all chips that this driver
supports, switch to always using it.

A slight confusion here is that the previously used command was incorrectly
named USLCOM_BAUD_RATE - even though we no longer use it, rename it to
USLCOM_SET_BAUD_DIV to closer match the name used in the datasheet.

This change reflects a similar change made in the Linux driver, which was
submitted by preston.fick at silabs.com, and has been tested on all of the
uslcom(4) devices I have to hand.
