mmc: core: Add runtime PM calls for debugfs/sysfs entries

Few debugfs/sysfs entries may require access to host and card.
Currently, read/write to these entries are not updated with
mmc_rpm_hold and mmc_rpm_release APIs due to which the device
is not getting resumed if it is already runtime suspended.
Fix this by calling those APIs at relevant code paths.
