[PATCH] dt-bindings: ufs: qcom: Add msi-parent for UFS MCQ

[Ziqi Chen]

The Message Signaled Interrupt (MSI) has been used
by UFS driver since the MCQ be enabled. Hence in UFS
DT node, we need to give the msi-parent property that
point to the hardware entity that serves as the MSI
controller for this UFS controller.
