irqchip/gic-v3-its: Correctly fish out the DID for platform MSI
Similarly to PCI where msi-map/msi-mask are used to compute the full RID
(aka DID in ITS speak), use the msi-parent as the discovery mechanism,
since there is no way a device can generally express its ID.
However, since switching to a per-device MSI domain model, the domain
passed to its_pmsi_prepare() is the wrong one, and points to the device's
instead of the ITS'. Bad.
Use the parent domain instead, which is the ITS domain.
