jtag: drivers: xlnx-pcie-xvc: Add support for SWD mode.

Add support for SWD debug to the Xilinx XVC/PCIe driver.

This is possible since the device is essentially a shift-register.
So doing SWD vs JTAG is a matter of wiring things correctly on the
RTL side (use TMS for SWDI, TDO for SWDO).

The clang static checker doesn't find any new problems with this change.
