By allowing platform MSI domain to be created on ACPI platforms, a platform device MSI domain can be set-up when it is probed. In order to do that, the MSI domain the platform device connects to should be retrieved, so the iort_get_platform_device_domain() is introduced to retrieve the domain from the IORT kernel layer. With the domain retrieved, we need a proper way to set the domain to platform device. Given that some platform devices (irqchips) require the MSI irqdomain to be their interrupt parent domain, the MSI irqdomain should be determined before platform device is probed but after the platform device is allocated which means that the code setting up the MSI irqdomain, ie acpi_configure_pmsi_domain() should be called in acpi_platform_notify() (that is triggered after adding a device but before the respective driver is probed) for the platform MSI domain code set-up path to work properly.
