soc: same70, samv71: free TRACESWO pin when unused

Pin PB5 is part of ARM Cortex-M debug interface and by default
configured to output TDO/TRACESWO signal. Disable TDO/TRACESWO
function on PB5 pin when LOG_BACKEND_SWO is not enabled. This
ultimately frees the pin to be used by standard SoC peripherals.
