PM_OPP is a helper library used by several of the existing cpufreq drivers. Some of the drivers select this symbol while others depend on it and rely on the architecture to enable it. Make this behaviour more consistent and obvious by having all the drivers select the symbol. This will also allow better build coverage of the affected drivers.
