scsi: ufs: dt-bindings: Add msi-parent for UFS MCQ
The Message Signaled Interrupts (MSI) support has been introduced in UFSHCI
version 4.0 (JESD223E). The MSI is the recommended interrupt approach for
MCQ. If choose to use MSI, in UFS DT, we need to provide msi-parent
property that point to the hardware entity which serves as the MSI
controller for this UFS controller.
