arm: stm32mp: spl: update error management in board_init_f

Call hang when an error is detected for probe of any driver
needed for console or DDR init: clk, reset and pincontrol

NB: previous behavior with a return in board_init_f() was not correct;
    DDR is not initialized and SPL execution can't continue
