PM: EM: Fix incorrect description of the cost field in struct em_perf_state
Due to commit 1b600da51073 ("PM: EM: Optimize em_cpu_energy() and remove
division"), the logic for energy consumption calculation has been modified.
The actual calculation of cost is 10 * power * max_frequency / frequency
instead of power * max_frequency / frequency.
Therefore, the comment for cost has been updated to reflect the correct
content.
