[PATCH v2] arm64: dts: qcom: sc8280xp: Fix GPU SMMU context fault interrupts

[Xilin Wu]

The GPU SMMU interrupt list includes PMU interrupts as the first two
context fault interrupts. This makes the driver register context fault
handlers on the wrong IRQs, leaving translation faults unhandled and
potentially stalling the GPU and preventing recovery.

Replace the context interrupt list with SPIs 680 through 688 and 703 in
context bank order to describe all ten hardware context interrupts.
