Merge #1149
1149: Add samples for nrf5340 r=lulf a=Tiwalun Samples for the nrf5340, copied from the existing nrf samples. Not sure if copying them is the best way of adding support, or using features in the existing samples would be better? The code is mostly the same, with some different peripherals and pin mappings for the DK. Co-authored-by: Dominik Boehi <dominik.boehi@gmail.com>
