The socfpga gen5 SPL manually zeroed bss in board_init_f(). Now that the DDR driver does not use bss any more, bss is not used before board_init_r() and we can remove this hack.
bss is normally zeroed by crt0.S, but after board_init_f(), before board_init_r(). socfpga just had this double-zeroing because it invalidly used bss in board_init_f() already (during DDR initialization).
