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.
