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

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.
