It seems maxItems should have been 4 in the first place and should remain
unchanged after removing the load state power domain. With this patch:

  - if:
      properties:
        compatible:
          contains:
            enum:
              - qcom,sc7180-mpss-pas
    then:
      properties:
        power-domains:
          items:
            - description: CX power domain
            - description: MX power domain
            - description: MSS power domain
        power-domain-names:
          items:
            - const: cx
            - const: mx
            - const: mss
