media: cx23885: add more quirks for reset DMA on some AMD IOMMU
The folowing AMD IOMMU are affected by the RiSC engine stall, requiring a reset to maintain continual operation. After being added to the broken_dev_id list the systems are functional long term. 0x1481 is the PCI ID for the IOMMU found on Starship/Matisse 0x1419 is the PCI ID for the IOMMU found on 15h (Models 10h-1fh) family 0x5a23 is the PCI ID for the IOMMU found on RD890S/RD990 Signed-off-by: Brad Love <brad@nextdimension.cc> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
