arm64: dts: qcom: qdu1000: add missing qcom,smmu-500 fallback

Since commit 6c84bbd103d8 ("dt-bindings: arm-smmu: Add generic
qcom,smmu-500 bindings") the SMMU is supposed to use qcom,smmu-500
compatible fallback:

  ['qcom,qdu1000-smmu-500', 'arm,mmu-500'] is too short
  ['qcom,qdu1000-smmu-500', 'arm,mmu-500'] is too long
