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.
