scsi: ufs: set peer device DL layer timers for TC1

Currently we don't set these PAPowerModeUserData[3..5] parameters in
PACP_PWR_Req frames, so all the DL layer timers for TC1 on peer device side
are 0s. This change sets the PAPowerModeUserData[3..5] to UniPro
specification recommended default values.
