arm64: dts: qcom: pm6150: correct USB VBUS regulator compatible

The first part of the compatible of USB VBUS node misses ending quote,
thus we have one long compatible consisting of two compatible strings
leading to dtbs_check warnings:

  sc7180-idp.dtb: usb-vbus-regulator@1100: compatible:0: 'qcom,pm6150-vbus-reg,\n qcom,pm8150b-vbus-reg' does not match '^[a-zA-Z0-9][a-zA-Z0-9,+\\-._/]+$'
  sc7180-idp.dtb: /soc@0/spmi@c440000/pmic@0/usb-vbus-regulator@1100: failed to match any schema with compatible: ['qcom,pm6150-vbus-reg,\n          qcom,pm8150b-vbus-reg']
