[PATCH] ARM: OMAP2+: clock: cleanup CPUfreq leftovers

[Kevin Hilman]

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.

Paul, now that the CPUfreq driver is in mainline (v3.3), this can be safely
removed.
