boards: nrf5340dk_nrf5340: properly choose UARTE pins for Network MCU 



When building for nRF5340 Application MCU we need to properly
select which are the default GPIO port/pins for UARTE on the
Network MCU (so we allocate them to Network MCU). These  depend
on the actual version of the board we are using (PDK or DK) so
this commit implements the corresponding conditional logic.
