scsi: ufs: core: Use local_clock() for debugging timestamps
CLOCK_MONOTONIC is not advanced when the system is in suspend. This becomes
problematic when debugging issues related to suspend-resume: the timestamps
printed by ufshcd_print_trs can not be correlated with dmesg entries, which
are timestamped with local_clock().
Change the used clock to local_clock() for the informational timestamp
variables and adds mirroring *_local_clock instances for variables used in
subsequent derevations (to not change the semantics of those derevations).
