Stanley Chu 58b60a9cb2 scsi: ufs: Introduce ufshcd_get_pwr_dev_param
ufshcd_get_pwr_dev_param defines an interface for power mode management
currently used by both ufs-qcom and ufs-hisi. Move the interface to ufs
core so every driver can take advantage of it.

Arnd Bergmann 176eb92774 scsi: ufs: hisi: fix ufs_hba_variant_ops passing
Without CONFIG_OF, the of_match_node() helper does not evaluate its
argument, and the compiler warns about the unused variable:

drivers/scsi/ufs/ufs-hisi.c: In function 'ufs_hisi_probe':
drivers/scsi/ufs/ufs-hisi.c:673:17: error: unused variable 'dev' [-Werror=unused-variable]

Rework this code to pass the data directly, and while we're at it,
correctly handle the const pointers.

Yaniv Gardi 47555a5c8a 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.
