Subject: [PATCH qcom v2] spi: dt-bindings: qcom,spi-geni-qcom: allow three interconnects

Recent Qualcomm Geni SPI nodes, e.g. on SM8450, come also with three
interconnects.  This fixes dtbs_check warnings like:

  sm8450-qrd.dtb: spi@...000: interconnects: [[46, 1, 0, 46, 4, 0], [47, 2, 0, 48, 12, 0], [49, 1, 0, 50, 1, 0]] is too long
  sm8450-qrd.dtb: spi@...000: interconnect-names: ['qup-core', 'qup-config', 'qup-memory'] is too long

Fixes: 5bdcae1fe1c5 ("spi: dt-bindings: qcom,spi-geni-qcom: convert to dtschema")
