With commit dc7b32ea4a00 ("armv7m_trace: get rid of the old tpiu
code") the target's event "trace-config" has been deprecated.
Create the TPIU device.
Replace the target's event "trace-config" with tpiu's event
"pre-enable" in the STM32 devices that require enabling the trace
clock _before_ programming the TPIU.
Make the script multi-instance-able in case it's used for JTAG
chained devices.
Uniform the code in STM32F4x with the other scripts.
Remove the empty event from STM32WLx.
