[PATCH v3 20/27] media: rockchip: rga: share the interrupt when an external iommu is used

[Sven Püschel]

From: Michael Olbrich <m.olbrich@xxxxxxxxxxxxxx>

The RGA3 and the corresponding iommu share the interrupt. So in that
case, request a shared interrupt so that the iommu driver can request
it as well.
