[PATCH u-boot-marvell 1/1] clk: armada-37xx-periph: fix DDR PHY clock divider values

Register value table for DDR PHY clock divider are wrong. They should be
0 or 1 for divide-by-2 or divide-by-4, respectively. Not 1 or 2. Current
values do not make sense, since 2 cannot be achieved, because the
register is only 1 bit long (mask is set to 1).

This fixes clk dump reporting DDR PHY clock rate differently from Linux.
