    platforms/xgene: Make use of dt_device_get_address return value
    
    Currently function xgene_check_pirq_eoi assigns the return value of
    dt_device_get_address to a variable res but does not make use of it.
    Fix it by making use of res in the condition checking the result of a
    call to dt_device_get_address instead of checking the address stored in
    dbase.
