Add 16650 hardware flowcontrol support. Basically PR 3844 from
...
Dave Huang <khym@bga.com>, with added check for broken early versions
of the 16650, taken from the Linux driver.
This should be extended to use, for example, higher trigger levels for
the bigger 16650 FIFO, and its capability for using a smaller divisor
and thus higher speeds. But this patch is very useful for 16650 users
already.
