Based on dt-binding "This property should present when there is more than a
single SPI" that's also case that's why explicitly specify interrupt
affinity to avoid incorrect usage.

Changes in v2:
- Update commit message to remove OS content - reported by Laurent

This avoids the following error upon linux boot:
armv8-pmu pmu: hw perfevents: no interrupt-affinity property,
guessing.
