[PATCH v3 04/12] iommu: Add iris-vpu-bus to iommu_buses

[Vishnu Reddy <busanna.reddy@oss.qualcomm.com>]

From: Vikash Garodia <vikash.garodia@oss.qualcomm.com>

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.
