scsi: ufs: core: Add host quirk UFSHCD_QUIRK_MCQ_BROKEN_INTR
Quirk UFSHCD_QUIRK_MCQ_BROKEN_INTR is introduced for hosts that implement a
different interrupt topology from the UFSHCI 4.0 spec. Some hosts raise
per hw queue interrupt in addition to CQES (traditional) when ESI is
disabled.
Enabling this quirk will disable CQES and use only per hw queue interrupt.
