[PULL 03/28] Revert "sysbus: add irq_routing_notifier"

[Peter Maydell <peter.maydell@linaro.org>]

From: Bernhard Beschow <shentey@gmail.com>

The callback has been introduced in commit 715ca691daca ("sysbus: add
irq_routing_notifier") for use in VFIO platform. Meanwhile, VFIO
platform has been removed via commit 762c85543948 ("vfio: Remove 'vfio-
platform'") which was its only user. Remove this unused code.

This reverts commit 715ca691daca081108b33306faa6fa102f0df8d8.
