[PATCH v2 02/12] arm: stm32mp: spl: update error management in board_init_f

[Patrick Delaunay]

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

Changes in v2:
- simplify patch after Wolfgang review, as console init alway failed when
  drivers can't probe (remove printf after preloader_console_init call)
