scsi: ufs: make the UFS variant a platform device
This change turns the UFS variant (SCSI_UFS_QCOM) into a UFS
a platform device.
In order to do so a few additional changes are required:
1. The ufshcd-pltfrm is no longer serves as a platform device.
Now it only serves as a group of platform APIs such as PM APIs
(runtime suspend/resume, system suspend/resume etc), parsers of
clocks, regulators and pm_levels from DT.
2. What used to be the old platform "probe" is now "only"
a pltfrm_init() routine, that does exactly the same, but only
being called by the new probe function of the UFS variant.
