drivers: xds110: Fix errors in routine that toggles
TCK during nSRST assert/deassert code.

To support LPRF targets (CC13xx/CC26xx), TCK must be toggled
for 50 ms while nSRST is asserted and right after it is
released. This allows the core to halt in boot ROM before
code is run that might interfere with debug access.

The current routine has two issues. It shouldn't be run at
all if the target is using SWD. And the delay needs to
be a real-time 50 ms, so the number of TCK periods should
be calculated off the set speed.
