IORT revision C introduced SMMUv3 MSI support for control interrupts,
which introduced a device ID mapping index to retrieve the dev ID
and ITS parent.

This patch set reuse the existing APIs to retrieve the data to
configure the MSI, but doing special checks to not introduce regressions
for CPI/NC--->SMMU--->ITS cases, please refer to each patch for detail
commit message.
