cpufreq: ti-cpufreq: Convert to module_platform_driver
ti-cpufreq will be responsible for calling dev_pm_opp_set_regulators on platforms that require AVS and ABB regulator support so we must be able to defer probe if regulators are not yet available, so change ti-cpufreq to be a module_platform_driver to allow for probe defer.
