arm: socfpga: spl: Merge spl_board_init() into board_init_f()

The code in spl_board_init() should have been in board_init_f()
from the beginning, since it is code which configures system and
then starts DRAM. Thus, it cannot be in spl_board_init(), which
is called from board_init_r() , which already expects a working
DRAM.
