dt-bindings: soc: qcom: apr: Make qcom,protection-domain optional again

The protection domain functionality exists only in SoCs starting from
MSM8998 [1], while the APR bindings are also used on older platforms.

Commit 41288c305836 ("ASoC: dt-bindings: qcom,apr: Split services to
shared schema") made the "qcom,protection-domain" required but it
should remain optional to avoid dtbs_check warnings on older platforms,
e.g.:

arch/arm64/boot/dts/qcom/apq8096-db820c.dtb:
  apr: service@3: 'qcom,protection-domain' is a required property
  From schema: Documentation/devicetree/bindings/soc/qcom/qcom,apr.yaml
