Subject: [PATCH 1/4] arm64: dts: qcom: x1e80100: Add IRIS video codec

Add the IRIS video codec to accelerate video decoding/encoding. Copied
mostly from sm8550.dtsi, only the opp-table is slightly different for X1E.
For opp-240000000, we need to vote for a higher OPP on one of the power
domains, because the voltage requirements for the PLL and the derived
clocks differ (sm8550.dtsi has the same).
