Revert "Revert "mmc: Set suspend/resume bus operations if CONFIG_PM_RUNTIME is used""
This reverts commit 866353859bcd3328dd0be84e0f0ed6d1ba834772. Moving back
suspend and resume to dev_pm_ops to ensure that bus suspend is done before
device suspend and bus resume is done after device resume. Without bus
suspend and resume, there is a chance of some requests being scheduled
after device suspend or before device resume is done.
