[ARM] OMAP3 clock: optimize DPLL rate rounding algorithm
The previous DPLL rate rounding algorithm counted the divider (N) down
from the maximum to 1. Since we currently use a broad DPLL rate
tolerance, and lower N values are more power-efficient, we can often
bypass several iterations through the loop by counting N upwards from
1.
Peter de Schrijver <[email protected]> put up with several
test cycles of this patch - thanks Peter.
