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 along with mmc runtime PM for qualcomm controllers. Changes since V2: - Fixed one warning reported by kernel test robot. >> drivers/mmc/core/mmc.c:1975: warning: Function parameter or member 'host' not described in 'mmc_sleepawake' - Included name of the subystem/driver in the title of the series as suggested by Bryan O'Donoghue. - Enabled MMC_CAP_AGGRESSIVE_PM for qualcomm controller and posted as [V3,3/3] as suggested by Wenchao Chen. Changes since V1: - Did minor code cleanup as suggested by Avri Altman. - Added _mmc_resume gain data in commit message as suggested by Ulf Hansson. - Split patch in two patches.
