In order to know the motherboard type earlier, perform I/O ports initialisation and FPGA loading in board_early_init_f() instead of board_early_init_r().
This is needed to be able to load mpc8xx CPM microcode base on motherboard type and before starting to use the CPM.
Console is not available yet so remove the printfs.
