Bruce Evans 92d0aa20dc Work around UMC8669F and Startech UART bugs by not writing to the
divisor latch registers if the registers wouldn't change.

Use the default console cfcr setting while setting the divisor
latch registers for console i/o.  Input may be messed up by
transiently changing the cfcr.

Use a usual cfcr setting while setting the divisor latch registers
in the probe.  This shouldn't matter, but this is not the place to
test the UART's handling of 5 bit words.

Removed a stale devfs comment.
