This change adds the use of devfreq to MMC. Both eMMC and SD card will use it. For some workloads, such as video playback, it isn't necessary for these cards to run at high speed. Running at lower frequency, for example 52MHz, in such cases can still meet the deadlines for data transfers. Scaling d
