scsi: ufs: separate dependency between UFS_QCOM and UFSHCD_PLATFORM
This change disconnects the dependency between the SCSI_UFSHCD_PLATFORM
and SCSI_UFS_QCOM.
It does so by adding the following changes:
1. Introducing SCSI_UFS_QCOM as a platform device. Its probe
function registers a set of vops to its driver_data.
2. Adding an optional device tree sub-node, under SCSI_UFSHCD_PLATFORM.
Now, the probe function of SCSI_UFSHCD_PLATFORM invokes the probe
function of its sub-node (if it exists), by calling
of_platform_populate(). It ensures that vops are set, and ready to
be used, by the time the UFSHCD driver starts its initialization
procedure.
