Ulrich Hecht 90afa5255f serial: sh-sci: fix hardware RX trigger level setting ...

1. Do not set the RX trigger level for software timeout devices on reset;
there is no timeout by default, and data will rot.
2. Do set the RX trigger level for hardware timeout devices when set
via sysfs attribute.

Fixes SCIFA-type serial consoles.
