Qualcomm IPQ8074 has tsens v2.3.0 block, though unlike existing v2 IP it
only uses one IRQ, so tsens v2 compatible cannot be used as the fallback.

We also have to make sure that correct interrupts are set according to
compatibles, so populate interrupt information per compatibles.

Changes in v4:
* Add the forgotten Reviewed-by tag from Krzysztof

Changes in v3:
* Remove implied min/maxItem properties as pointed by Rob

Changes in v2:
* No need for a list in compatible check
* Specify minItems and maxItems for interrupt and interrupt-names
