ftdi: Enable SWDIO output before sending data on it
The SWDIO buffer has to be enabled, by setting SWDIO_OE, for data on
SWDIO to reach the target. Explicitly do this before sending the
switch sequences for JTAG-to-SWD, etc.
This makes the code insensitive to the state of SWDIO_OE specified in
ftdi_layout_init. It used to work only on adapters with a non-inverted
SWDIO_OE inited to 1, or inverted SWDIO_OE inited to 0.
