Not all RPM firmware versions have the dynamic sleep stats offset available. Most older versions use a fixed offset of 0xdba0. Add support for this using new SoC-specific compatibles for APQ8084, MSM8226, MSM8916 and MSM8974. Even older SoCs seem to use a different offset and stats format. If needed those could be supported in the future by adding separate compatibles for those with a different stats_config.
