The patch currently under review to enable ARM cpufreq drivers for ARM64 which is useful due to the large amount of shared IP between ARM and ARM64 SoCs. However the big.LITTLE switcher relies on an architecture interface to build which is not present on ARM64. Add a dependency until that is resolved.

From: Mark Brown broonie@linaro.org
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.
