The 4430 OPP table was being registered for all other OMAP4 variants too, like 4460 and 4470 causing issues with cpufreq driver enabled. 4460 and 4470 devices have different OPPs as compared to 4430, and they should be populated seperately. As long as that happens, let the OPP table registeration happen only on 4430 device.
