scsi: ufs: sysfs: power descriptor
This patch introduces a sysfs group entry for the UFS power descriptor
parameters. The group adds "power_descriptor" folder under the UFS driver
sysfs entry (/sys/bus/platform/drivers/ufshcd/*). The parameters are shown
as hexadecimal numbers. The full information about the parameters could be
found at UFS specifications 2.1.
