boards: nordic: nrf7120pdk: Set nRF7120 default console to UART30

The nrf7120 CI Setup requires the console UART to be routed
to fixed pins on P0 on the I/O board.UART20 is unable to
operate on P0 as it only supports pin-mapping to P1 or P3
.This PR sets UART30 as the default console , which
supports P0 pin mappings.This change ensures compatibility
 with Pinset A in CI runs and removes the need for overlay workarounds.
