boards: nordic: nrf54h20dk: ETM in JLinkScript
The JLinkScript originally configured more than needed which reduces readability, so stripped it down to the minimum. At the same time improved behavior under reset and added ETM to the radiocore JLinkScript. Signed-off-by: Karsten Koenig <[email protected]>
