uartfax.c: fix for old Openmoko bug with Auto-CTS
Openmoko made the change of enabling hardware assisted CTS flow control
in the UART when RTS/CTS flow control is used - it is a change which we
have retained in FreeCalypso - but they forgot to turn this hw mode off
if RTS/CTS flow control is deselected at the application level. We
(FreeCalypso) are now fixing the latter defect ourselves.
