driver/ftdi: skip trst in swd mode
When using the adapter olimex arm-jtag-swd (to convert to SWD a
JTAG-only FTDI adapter), the pin trst on JTAG side is re-used to
control the direction of pin SWDIO on SWD side.
There is a single reset API at adapter driver to assert/deassert
either srst and/or trst. A request to assert/deassert srst can
cause also trst to change value, hanging the SWD communication.
In SWD mode, ignore the value passed to trst.
