clk: sunxi: Fix incorrect usage of round_down()
round_down() can only round to powers of 2. If round_down() is asked
to round to something that is not a power of 2, incorrect results are
produced. The incorrect results can be both too large and too small.
Instead, use rounddown() which can round to any number.
