Top level QUP node(patch#18) includes i2c,spi,uart nodes.
soc/qcom/qcom,geni-se.yaml validate those subnodes against respective
yaml. The example that is added in YAML file for QUP node will not find
sa8255p compatibles if all 4 yaml(qup, i2c, spi, serial nodes) are not
included in the same series.
