arm64: dts: qcom: msm8996: fix APR services nodes

DT schema expects APR services node names to be "service" and to have an
unit address (as it has a "reg" property):

  qcom/msm8996-xiaomi-gemini.dtb: apr: 'power-domains', 'q6adm', 'q6afe', 'q6asm', 'qcom,smd-channels' do not match any of the regexes: '^service@[1-9a-d]$', 'pinctrl-[0-9]+'
