[PATCH v4 4/6] dt-bindings: PCI: snps,dw-pcie: Add msi-parent for MSI handle check

The IMSIC device on RISC-V based system does not require ID
remapping for MSI. So this device only needs "msi-parent"
property for IMSIC-based SoC, and the "msi-map" is not a
necessary property.

Add new condition for MSI handling on IMSIC based SoC.
