[PATCH] scsi: ufs: Disable autohibern8 feature in Cadence UFS

[sheebab]

This patch disables autohibern8 feature in Cadence UFS. 
The autohibern8 feature has issues due to which unexpected interrupt
trigger is happening. After the interrupt issue is sorted out autohibern8
feature will be re-enabled
