Actually MULT_ROUND_UP made my life difficult earlier, and finally came up
with this solution instead of removing it.

It was something like 60000000 requested of PLL, for i = 1, but for other
values, it was something like 60000001, 60000002 etc.

Even if round rate rounds, I thought removing MULT_ROUND_UP would be ok,
couldn't spend time to understand fully rational behind it, and as it was
in generic code, kept away from doing it.

Afzal
