scsi: ufs: add quirk to increase host PA_SaveConfigTime The maximum value PA_SaveConfigTime is 250 (10us) but this is not enough for some vendors. Gear switch from PWM to HS may fail even with this max. PA_SaveConfigTime. Gear switch can be issued by host controller as an error recovery and any software delay will not help on this case so we need to increase PA_SaveConfigTime to >32us as per vendor recommendation. This change adds a quirk to increase the PA_SaveConfigTime parameter.
