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.
