OMAP2+: clock: remove the DPLL rate tolerance code
Remove the DPLL rate tolerance code that is called during rate rounding. As far as I know, this code is never used, since it's been more important for callers of the DPLL round_rate()/set_rate() functions to obtain an exact rate than it is to save a relatively small amount of power.
