Add iris-vpu-bus to iommu_buses[] to register the bus notifier callbacks
for device add and removal events. This ensures that when a device is
registered on iris-vpu-bus, the notifier triggers dma_configure(),
which sets up the IOMMU context for that device.

We have added vpu platform bus as suggested by you earlier. Patches #1 and #2 in this series adds the same. Please review and suggest if you have any comments.

Please provide an immutable tag by applying patch #1 and #2, we can then have that in media tree and apply remaining patches in this series.

If you have any other suggestion to land these patches, please suggest.

Regards,
Vikash
