Currently ufshcd driver assumes that bInitPowerMode parameter is not changed by any vendors thus device power mode can be set as "Active" during initialization. According to UFS JEDEC specification, device power mode shall be "Active" after HW Reset is triggered if the bInitPowerMode parameter in Device Descriptor is default value. By above description, we can set device power mode as "Active" after device reset is triggered by vendor's callback. With this change, the link startup performance can be improved in some cases by not setting link_startup_again as true in ufshcd_link_startup().
