scsi: ufs: core: Increase the START STOP UNIT timeout from one to ten seconds

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")
