The DT binding filename and compatible string do not match (qcom,qaif-cpu.yaml vs qcom,shikra-qaif-cpu).
Usually DT binding filenames are aligned with the compatible string for clarity.
Is there a reason for the naming mismatch?

Could we use the standard GIC and IRQ type macros instead of raw values here for readability?
Ex: interrupts = <GIC_SPI 331 IRQ_TYPE_LEVEL_HIGH>;
