UBUNTU: SAUCE: iommu: intel-ipu: use IOMMU passthrough mode for Intel IPUs on Raptor Lake

BugLink: https://bugs.launchpad.net/bugs/1989041

Intel IPU(Image Processing Unit) has its own (IO)MMU hardware,
The IPU driver allocates its own page table that is not mapped
via the DMA, and thus the Intel IOMMU driver blocks access giving
this error: DMAR: DRHD: handling fault status reg 3 DMAR:
[DMA Read] Request device [00:05.0] PASID ffffffff
fault addr 76406000 [fault reason 06] PTE Read access is not set
As IPU is not an external facing device which is not risky, so use
IOMMU passthrough mode for Intel IPUs.
