Subject: [PATCH 0/4] arm64: dts: qcom: x1e80100: Add IRIS video codec

Add the necessary definitions to enable the IRIS video codec for
accelerated video decoding on the X1E CRD and Lenovo ThinkPad T14s. The
additions are largely copied as-is from sm8550.dtsi with some minor changes
necessary for X1E.

The PAS interface used to boot the IRIS firmware is not functional in EL2.
The code to start it without using PAS exists already in the Venus driver,
but was not ported over to IRIS yet. Discussions how to model the
video-firmware IOMMU are still ongoing, so disable IRIS in x1-el2.dtso for
now to avoid regressions when running in EL2.
