scsi: ufs: ufs-qcom: Change UFS devfreq timer to delayed 



Devfreq uses the default DEVFREQ_TIMER_DEFERRABLE mode which uses the
deferred timer for scheduling the devfreq load monitor function.  This
causes the load monitoring to be done only with non-idle CPUs and not
making use of the idle CPUs.

Hence, use the DEVFREQ_TIMER_DELAYED mode which uses the delayed timer
thereby making use of idle CPUs as well for load monitoring.
