[patch] clk: vt8500: several forever loops

[Dan Carpenter]

This does a bunch of looping like this:

	for (div2 = 7; div2 >= 0; div2--)

But unsigned values are always greater than or equal to zero so it just
loops and loops.  Really "mul", "div1" and "div2" should all be declared
as int for cleanliness sake.
