One UFS vendor asked to increase the UFS timeout from 1 s to 3 s.
Another UFS vendor asked to increase the UFS timeout from 1 s to 10 s.
Hence this patch that increases the UFS timeout to 10 s. This patch can
cause the total timeout to exceed 20 s, the Android shutdown timeout.
This is fine since the loop around ufshcd_execute_start_stop() exists to
deal with unit attentions and because unit attentions are reported
quickly.
Fixes: dcd5b7637c6d ("scsi: ufs: Reduce the START STOP UNIT timeout")
Fixes: 8f2c96420c6e ("scsi: ufs: core: Reduce the power mode change timeout")
