Module Name:    src
Committed By:   jakllsch

Modified Files:
        src/sys/dev/usb: uchcom.c

Log Message:
Remove UCHCOM_REG_BPS_MOD and UCHCOM_REG_BPS_PAD usage.

There is no clear indication doing these calculations and setting the
resulting register bits results in improved functionality.  Contrary
to hints in the code, short-term precision of the UART clock doesn't
appear to improve when these bits are adjusted.

Neither the vendor's Linux driver nor the mainline Linux driver
currently touch these bits.

Tested with CH341A and a logic analyzer.
