UPSTREAM: scsi: ufs: qcom: Enable RPM_AUTOSUSPEND for runtime PM

Browse Source 
In order to allow the block devices to enter autosuspend mode during
runtime, thereby allowing the ufshcd host driver to also runtime suspend,
let's make use of the RPM_AUTOSUSPEND flag.

Without this flag, userspace needs to enable the autosuspend feature of
the block devices through sysfs.
