IORT shows representation of IO topology for ARM based systems.
It describes how various components are connected together on
parent-child basis e.g. PCI RC -> SMMU -> ITS.
Initial support allows to:
- register ITS MSI chip along with ITS translation ID and domain token
- find registered domain token based on ITS translation ID
- find registered domain token corresponding to given PCI device
- find PCI device DeviceID based on its RequesterID
Additional features like:
- devices to SMMU binding
- finding platform device DeviceID based on its RequesterID
will be added in next series.

As per kbuild test report, this has to be:
#ifdef CONFIG_IORT_TABLE
Will be fixed in the next version.
