mmc: core: Dynamic freq scaling for SD,MMC,SDIO
Added support for dynamic frequency scaling of SD,MMC,SDIO devices.
The device is registered with devfreq framework after enumeration if
CONFIG_MMC_FREQ_SCALING is enabled.
MMC frequency governor is added to dynamically scale the frequency.
The governor doesn't use central polling but schedules a work to poll
the status of the device periodically. Optional callbacks are provided
to have custom algorithms for determining the frequency.
