Now that we have OPP layer, and OMAP CPUfreq driver is using it, we no
longer need/use the clock framework code for filling up CPUfreq
tables. Remove it.
Thanks to Russell King for pointing out the parts I missed under
plat-omap in the original version.

Paul, this is an updated version of the previous one after a different
CPUfreq patch from Russell made me realize I missed the plat-omap pieces.
