omap3_noncore_dpll_set_rate uses omap2_dpll_round_rate explicitly.  Instead
use the struct clk pointer's round_rate function to allow for DPLL's with
special needs.

Also the rounded rate can differ from target rate, so to better reflect
reality set clk->rate equal to the rounded rate when setting DPLL frequency.
This avoids issues where the DPLL frequency is slightly different than what
debugfs clock tree reports using the old target rate.

An example of both of these needs is DPLL_ABE on OMAP4 which can have a 4x
multiplier on top of the usual MN dividers depending on register settings.
This requires a special round_rate function that might yield a rate
different from the initial target.

The two separate changes in this patch have been separated out into two
patches - both included below.  Please let me know if you have any
comments; otherwise, I'll queue for 3.2.

Yes, looks good to me. Thanks. Jon
