scsi: ufs: disable interrupt aggregation if not supported

UFS host controller specification allows the interrupt aggregation for
receiving single interrupt for multiple command completions. But some of
the UFS host controller implementation might have this feature not
supported or broken for some reason and such deviation from spec. should be
specified by setting UFSHCD_QUIRK_BROKEN_INTR_AGGR quirk.

This change make sure that if UFSHCD_QUIRK_BROKEN_INTR_AGGR quirk is set
then interrupt aggregation logic would be disabled hence controller should
raise interrupt after every command completion.
