[0/2] arm64: allwinner: h6: Add IOMMU reference to Hantro G2 decoder

Message

While doing some decoder tests with Fluster and Chrome's VDA tests, I
found that the Hantro G2 was failing, and there were IOMMU fault errors
in the kernel log.

Turns out the decoder is behind the IOMMU on the H6, as shown in the
user manual.

This series adds the "iommus" property to the binding and the dtsi.
Please have a look.


Thanks
ChenYu
