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.
