Add the ability to partially initialize the MMC device by
using device sleep/awake sequence (CMD5).
Device will be sent to sleep state during mmc runtime/system suspend
and will be woken up during mmc runtime/system resume.
By using this sequence the device doesn't need full initialization
which gives 25% time reduction in system/runtime resume path.
Also enable this feature for qualcomm controllers.
