platform-msi: Make platform_msi_create_device_domain() ACPI aware
The irqdomain creation that is carried out in:
platform_msi_create_device_domain()
relies on the fwnode_handle interrupt controller token to associate the
interrupt controller with a specific irqdomain. Current code relies on
the OF layer to retrieve a fwnode_handle for the device representing the
interrupt controller from its device->of_node pointer. This makes
platform_msi_create_device_domain() DT specific whilst it really is not
because after the merge of commit f94277af03ea ("of/platform: Initialise
dev->fwnode appropriately") the fwnode_handle can easily be retrieved
from the dev->fwnode pointer in a firmware agnostic way.
Update platform_msi_create_device_domain() to retrieve the interrupt
controller fwnode_handle from the dev->fwnode pointer so that it can
be used seamlessly in ACPI and DT systems.
