With OMAP3+ and AM33xx supported SoC having defined CPU DT entries with operating-points defined, we can now use the SoC generic cpu0-cpufreq driver to start using it, lets now switch to the generic driver.
As part of this change, switch the dummy clock node to use cpufreq-cpu0. This is an suggested solution till we have OMAP clock nodes in DT. Once the DT conversion is complete, we can then do: clocks = <&dpll_mpu_ck>; or the SoC specific equivalent. Inspired by patch: https://patchwork.kernel.org/patch/2067841/ now made generic.
