This patch adds a new macro, em_is_microwatts(), which checks if the EM_PERF_DOMAIN_MICROWATTS flag is set for a given Energy Model. This macro enables other parts of the kernel, such as cooling devices, to easily determine the unit of power used by the Energy Model and to perform the necessary conversions if the values are provided in microwatts.
