As a proof of concept, change OMAP's cpufreq driver to use mpu_clk in
place of directly using the DPLL.  This better reflects reality as there
are some functional clks between the ARM IP and the PLL.

To make this work mpu_clk uses the new .round_rate function
omap2_passthrough_round_rate, which simplies passing up a rate change
request to the parent.

Not for merging, just to get discussion going around the common clk
patches and future OMAP adaptations.
